OPINION OF THE COURT
ADAMS, Circuit Judge.
On January 30, 1980, appellants Royce Kerchner and Bernard Ryan, inmates at the State Correctional Institution at Rock-view [Rockview] filed a class action civil rights complaint under 42 U.S.C. § 1983 seeking preliminary and final injunctive relief against two prison officials. Appellants contended that defendants were required by the sixth and fourteenth amendments to provide indigent inmates with free legal supplies including pads, pens, pencils, photocopying, and postage. Three issues are presented for consideration: first, whether the district court erred when it denied the inmates’ motion for a preliminary injunction; second, whether this Court has appellate jurisdiction to review at this time the district court’s denial of class certification; and finally, assuming there is jurisdiction over the denial of class certification, whether the trial court abused its discretion in denying class certification. We believe that the district court did not err in denying the motion for preliminary injunctive relief, and affirm the judgment of the district court in this regard. Because we conclude, however, that the order denying class certification is not now appealable, we do not reach the merits of the third issue.
I.
Kerchner and Ryan brought suit against Dr. J. F. Mazurkiewicz, the Superintendent of Rockview, and Gary R. Gerber, the Librarian at Rockview, for their alleged refusal to provide without cost certain legal supplies and documents both to the named plaintiffs and to other allegedly indigent inmates. In this respect, Pennsylvania law provides that: “Adequate legal size paper shall be available in institution commissaries for purchase by inmates.” 37 Pa.Code § 93.2(a). The inmate handbook for Rock-view further provides:
LEGAL MATERIAL AND NOTARY PUBLIC
1. You may purchase any legal material you believe to be valuable to you in seeking legal remedies. The amount permitted in your cell at any one time may be limited depending on individual circumstances.
2. Some legal materials are available at the institutional library for your use.
3. The institution will provide notary service for documents requiring notarization. A request slip should be directed to the Records Office in the institution for Notary Public Services.
Appendix at 37.
As a result of the operation of the above policy, Kerchner complains that he has been “forced ... to pay for legal supplies and materials in seeking ... legal remedies . . . despite his indigency and [has been] placed ... in the position of either foregoing these supplies and materials in the pursuit of legal remedies or giving up the few amenities available in prison life.” H 16, Plaintiffs’ Complaint, Appendix at 10.
Kerchner earns $35.00 per month from his institutional job. During his incarceration Kerchner has had less than $60.00 in his institutional account at any one time; his average balance through January 2, 1980 was approximately $21.72. Ryan’s average balance was $12.00; on January 2, 1980, he had $25.85 in his institutional account. Appendix at 19-23.
II.
At the outset it must be stressed that the appellants did not establish that there was any instance in which they were unable to pursue any legal action because of the cost of legal supplies and photocopying. Rather, they assert that in being required to use their own limited funds they have been or will be deprived of certain unspecified amenities. The first issue before us, then, is simply whether the district court erred in denying a preliminary injunction that would have required the Commonwealth to supply, without cost to the named plaintiffs, pads, pens, pencils, postage, photocopying and other legal materials when the plaintiffs had funds in their institutional accounts sufficient to purchase those items.
A.
A preliminary injunction is not granted as a matter of right. Eli Lilly & Co. v. Premo Pharmaceutical Laboratories, Inc., 630 F.2d 120, 136 (3d Cir.), cert. denied, 449 U.S. 1014, 101 S.Ct. 573, 66 L.Ed.2d 473 (1980). It may be granted, however, if the moving party demonstrates both a reasonable probability of eventual success in the litigation and that the party “will be irreparably injured pendente lite if relief is not granted.” Id. at 136; Kennecott Corp. v. Smith, 637 F.2d 181, 187 (3d Cir. 1980). The trial court may also consider the possibility of harm to other interested persons from the grant or denial of the injunction, as well as harm to the public interest. Eli Lilly & Co., 630 F.2d at 136. The grant or denial of a preliminary injunction is committed to the sound discretion of the district judge, who must balance all of these factors in making a decision. Penn Galvanizing Co. v. Lukens Steel Co., 468 F.2d 1021, 1023 (3d Cir. 1972). Consequently, the scope of appellate review of a trial court’s ruling is narrow. Unless the trial court abused its discretion, or committed an error in applying the law, we must take the judgment of the trial court as presumptively correct. Continental Group, Inc. v. Amoco Chemicals Corp., 614 F.2d 351, 357 (3d Cir. 1980).
In this instance, the case was referred to Magistrate Raymond J. Durkin, who wrote a thoughtful opinion and recommendation. He concluded that the plaintiffs failed to carry their burden to show either “a probability of success on the merits or that they will suffer irreparable harm if the preliminary injunction is not granted.” Appendix at 57. Magistrate Durkin found that
there has been no demonstration in the complaint or other documents that any prisoner has not been able to perfect and pursue a legal action due to the written policy concerning postage and the policy regarding paper and writing utensils, even if informal. With respect to the specific matters in dispute, it is recognized by plaintiffs that each inmate is permitted without cost to mail 10 one-ounce first class letters or the equivalent thereof in postage per month up to $1.50, and there has been no demonstration that any prisoner who exceeded this limit and was without funds and found himself in an emergency situation with respect to court matters was refused postage. In the absence of such demonstration, it would appear that prison officials would be free to establish some limitation on free postage.
* * * * * *
With respect to the matter of free photocopying, plaintiffs once again have not pointed to any instance in which an inmate was actually denied access to the courts by reason of being unable to photocopy documents when he did not have the funds to pay for the photocopying service.
Appendix at 58, 60. The district court approved and adopted the Magistrate’s recommendation to deny the preliminary injunction “for the reasons set forth in his report.” Appendix at 69.
B.
On appeal, the inmates reiterate their claim that they were irreparably harmed because they were forced into a position in which they had “to choose to forego legal remedies for the few ‘amenities of prison life’ they have funds to purchase, or forego these ‘amenities in pursuit of legal remedies.’ ” Appendix at 53. But appellants do not in any way specify what these amenities are. Nor do they allege that they were deprived of their basic necessities. They assert merely that they have “clear” constitutional rights that are being violated, and that the violation of constitutional rights for even minimal periods of time constitutes the required showing of irreparable harm. Jurisdiction is vested in this Court pursuant to 28 U.S.C. § 1292(a)(1).
It is now established, of course, “that prisoners have a constitutional right of access to the courts.” Bounds v. Smith, 430 U.S. 817, 821, 97 S.Ct. 1491, 1494, 52 L.Ed.2d 72 (1977). But at this stage in the litigation, there has been no showing that this proceeding involves “access to the courts.” Although broad constitutional claims are asserted, the present matter is quite different from any of the major constitutional cases relied upon by the appellants: This is not a situation in which prisoners are being denied the right to file petitions for habeas corpus unless the petitioners are found “properly drawn” by the legal investigator for the Parole Board. Ex parte Hull, 312 U.S. 546, 549, 61 S.Ct. 640, 641, 85 L.Ed. 1034 (1941). This is not a case in which the state has “effectively foreclosed” indigent prisoners from filing appeals and habeas corpus petitions by requiring the payment of docket fees. Smith v. Bennett, 365 U.S. 708, 81 S.Ct. 895, 6 L.Ed.2d 39 (1961); Burns v. Ohio, 360 U.S. 252, 257, 79 S.Ct. 1164, 1168, 3 L.Ed.2d 1209 (1959). This is not a case in which an indigent inmate cannot acquire trial records because of his inability to pay for them. Griffin v. Illinois, 351 U.S. 12, 20, 76 S.Ct. 585, 591, 100 L.Ed. 891 (1956). See also Draper v. Washington, 372 U.S. 487, 83 S.Ct. 774, 9 L.Ed.2d 899 (1963); Eskridge v. Washington Prison Board, 357 U.S. 214, 78 S.Ct. 1061, 2 L.Ed.2d 1269 (1958). L.Ed.2d 899 (1963). This is not a case in which indigent inmates are denied “a meaningful appeal” from their convictions because of the state’s failure to appoint counsel. Douglas v. California, 372 U.S. 353, 358, 83 S.Ct. 814, 817, 9 L.Ed.2d 811 (1963). This is not a case in which the state prison system failed to provide adequate legal library facilities, Bounds, supra. Nor is this a case in which the state is closing a prison law clinic and does not provide an adequate law library, Wade v. Kane, 448 F.Supp. 678 (E.D.Pa.1978), aff’d 591 F.2d 1338 (3d Cir. 1979). Plaintiffs have been permitted to proceed in forma pauperis in this and in all their other cases, and thus the case at hand is also unlike Souder v. McGuire, 516 F.2d 820 (3d Cir. 1975), in which the plaintiffs were denied the right to proceed in forma pauperis.
Appellants rely heavily on Bounds v. Smith, 430 U.S. 817, 97 S.Ct. 1491, 52 L.Ed.2d 72 (1977). In the very first sentence in Bounds, however, the majority stated its perception of the primary issue before the Court as follows: “The issue in this case is whether States must protect the right of prisoners to access to the courts by providing them with law libraries or alternative sources of legal knowledge.” 430 U.S. at 817, 97 S.Ct. at 1492-93 (emphasis added). Pads, pens, pencils, and photocopy machines are, of course, neither “law libraries” nor “alternative sources of legal knowledge.” In a lengthy discourse on somewhat collateral issues, however, the Court said: “It is indisputable that indigent inmates must be provided at state expense with paper and pen to draft legal documents, with notarial services to authenticate them, and with stamps to mail them.” 430 U.S. at 824-25, 97 S.Ct. at 1496 (emphasis added). Whether the latter statement was dictum or a holding is irrelevant for our purposes because the touchstone was the word “indigent,” though the Court proffered no definition of indigency.
Magistrate Durkin’s report suggests that the plaintiffs may not have been “indigent” for the purpose of purchasing the modest supplies at issue here. Further, and more important, the Magistrate stressed that there was no proof adduced that “any prisoner has not been able to perfect and pursue a legal action due to the written policy concerning postage and the policy regarding paper and writing utensils . . . . ” Appendix at 58. He noted that each inmate was allowed to mail ten first class letters without cost per month and found that plaintiffs were unable to point “to any instance in which an inmate was actually denied access to the courts by reason of being unable to photocopy documents when he did not have the funds to pay for the photocopying service.” Appendix at 60. We agree with the district court that appellants have not met their burden of showing irreparable injury in this regard. As the Court of Appeals for the Tenth Circuit recently observed in Johnson v. Parke:
The constitutional concept of an inmate’s right of access to the courts does not require that prison officials provide inmates free or unlimited access to photocopying machinery. See Harrell v. Keo-hane [621 F.2d 1059 (10th Cir. 1980)]. When an inmate’s access to the courts is not unduly hampered by the denial of access to such machinery, he cannot complain.
642 F.2d 377, 380 (10th Cir. 1981) (emphasis added).
We therefore will affirm the district court’s order denying appellants’ motion for preliminary injunctive relief.
IIÍ.
Appellants urge that, in addition to ruling on the preliminary injunction issue, we should also consider that portion of the district court’s order that denied certification of the purported class of inmates. We conclude, however, that we lack appellate jurisdiction at this time over the latter issue.
A.
The appealability of a district court order denying a motion for class certification was, until recently, an unresolved issue. In 1978, however, the Supreme Court established that such orders are not generally appeala-ble, inasmuch as they are neither “final decisions” for purposes of 28 U.S.C. § 1291, Coopers & Lybrand v. Livesay, 437 U.S. 463, 98 S.Ct. 2454, 57 L.Ed.2d 351 (1978), nor refusals of injunctive relief for purposes of 28 U.S.C. § 1292(a)(1), Gardner v. Westinghouse Broadcasting Co., 437 U.S. 478, 98 S.Ct. 2451, 57 L.Ed.2d 364 (1978). Cf. DeMasi v. Weiss, 669 F.2d 114 at 119 (3d Cir. 1982) (refusing to employ mandamus to review class certification order). In the present case, however, class certification was denied in the same order as the refusal of preliminary injunctive relief. Both parties agree that this Court has jurisdiction, under section 1292(a)(1), to review that portion of the order declining to issue the requested injunction. The disputed question is whether we may also review the class certification issue that was disposed of in the same order.
Appellants exhort us to embrace what one federal court has termed the doctrine of “pendent appellate jurisdiction,” Marcera v. Chinlund, 595 F.2d 1231, 1236 n.8 (2d Cir.), vacated on other grounds sub nom. Lombard v. Marcera, 442 U.S. 915, 99 S.Ct. 2833, 61 L.Ed.2d 281 (1979). That doctrine, a judicially crafted exception to the interlocutory appeal rules of 28 U.S.C. § 1292, would provide that once an appellate court is accorded jurisdiction over the grant, refusal or modification of an injunction pursuant to § 1292(a)(1), the court in its discretion may review the entire order, including those portions of the order which otherwise would not qualify for interlocutory review.
While the Supreme Court has yet to address the propriety of pendent appellate jurisdiction, our circuit has had a number of opportunities to explore the concept. An examination of the opinions reveals, however, that this Court has never formulated a consistent approach to the problem. In several decisions, this Court appears to have adopted a broad view of appellate jurisdiction under section 1292. In D’Iorio v. County of Delaware, 592 F.2d 681 (3d Cir. 1978), for example, the Court stated:
[B]ecause the district court granted D’lorio’s requested injunctive relief and ordered his reinstatement as a county detective, this appeal is properly before us under 28 U.S.C. § 1292(a)(1) (authorizing appeals from injunctive orders). When appellate jurisdiction is established on this basis, the entire order, and not simply the propriety of the injunctive relief, is before the court for review.
592 F.2d at 685 n.4 (emphasis added). Similarly, in Kohn v. American Metal Climax, Inc., 458 F.2d 255 (3d Cir.), cert. denied, 409 U.S. 874, 93 S.Ct. 120, 34 L.Ed.2d 126 (1972), the Court asserted that certain provisions of the district court’s orders were “injunctions within the meaning of section 1292(a)(1) .... Given jurisdiction over these aspects of the district court’s orders we can review the merits of the entire case as it now rests.” 458 F.2d at 262. See also Jaffee v. United States, 592 F.2d 712, 715 (3d Cir.), cert. denied, 441 U.S. 961, 99 S.Ct. 2406, 60 L.Ed.2d 1066 (1979); Merrell-National Laboratories, Inc. v. Zenith Laboratories, Inc., 579 F.2d 786, 791 (3d Cir. 1978).
The reach of Kohn, however, was explicitly constricted in W. L. Gore & Assoc. v. Carlisle Corp., 529 F.2d 614, 618 (3d Cir. 1976), a patent infringement case in which Judge Maris, writing for a unanimous panel, concluded that
the jurisdiction conferred upon the court of appeals does not extend to other claims or issues determined by the judgment which have no bearing upon the propriety of the action of the court with respect to the injunction.... Our decision in Kohn ... is not to the contrary. For in that case an injunction was the principal relief sought and all the issues decided by the district court in its interlocutory judgment which was appealed under § 1292(a)(1) appear to have been involved in the plaintiff’s right to injunctive relief.
Finally, a later case, Concerned Citizens of Bushkill Township v. Costle, 592 F.2d 164, 168 (3d Cir. 1979), would appear to be even more directly at variance with Kohn and D’Iorio. Considering a district court order that disposed both of plaintiff’s motion for a preliminary injunction and of defendant-intervenor’s motion to file a supplemental answer, the court stated summarily: “This court’s jurisdiction is limited to reviewing that portion of the .. . order refusing to grant an injunction.” Bushkill thus represents a narrow approach to section 1292(a)(1) that would restrict our jurisdiction to the literal terms of the statute.
B.
Section 1292(a)(1) provides that the appellate courts “shall have jurisdiction of appeals from .. . [ijnterloeutory orders of the district courts . . . granting, continuing, modifying, refusing or dissolving injunctions, or refusing to dissolve or modify injunctions. ... ” 28 U.S.C. § 1292(a)(1) (1976). The provision is one of four exceptions to the general rule that our appellate jurisdiction extends to final decisions of district courts. 28 U.S.C. § 1291 (1976). The history of § 1292 has been recounted elsewhere, see, e.g., Baltimore Contractors, Inc. v. Bodinger, 348 U.S. 176, 75 S.Ct. 249, 99 L.Ed. 233 (1955); Katz v. Carte Blanche Corp., 496 F.2d 747, 753-54 (3d Cir.), cert. denied, 419 U.S. 885, 95 S.Ct. 152, 42 L.Ed.2d 125 (1974); Stewart-Warner Corp. v. Westinghouse Electric Corp., 325 F.2d 822, 829-30 (2d Cir. 1963) (Friendly, J., dissenting), cert. denied, 376 U.S. 944, 84 S.Ct. 800, 11 L.Ed.2d 767 (1964). It is sufficient to note here that section 1292(a)(1) “creates an exception to the long-established policy against piecemeal appeals, which this Court is not authorized to enlarge or extend. The exception is a narrow one and is keyed to the ‘need to permit litigants to effectually challenge interlocutory orders of serious, perhaps irreparable, consequence.’ ” Gardner v. Westinghouse Broadcasting Co., 437 U.S. 478, 480, 98 S.Ct. 2451, 2453, 57 L.Ed.2d 364 (1978) (quoting Baltimore Contractors v. Bodinger, 348 U.S. 176, 181, 75 S.Ct. 249, 252, 99 L.Ed. 233 (1955) (footnote omitted)); accord, Carson v. American Brands, Inc., 450 U.S. 79, 101 S.Ct. 993, 67 L.Ed.2d 59 (1981). Because section 1292(a)(1) is an exception to an otherwise fundamental rule of federal appellate jurisdiction, we must construe the scope of the provision with great care and circumspection. Indeed, as the Supreme Court declared in Switzerland Cheese Assoc. v. E. Horne’s Market, Inc., 385 U.S. 23, 24, 87 S.Ct. 193, 195, 17 L.Ed.2d 23 (1966), it is necessary that we “approach this statute somewhat gingerly lest a floodgate be opened that brings into the exception many pretrial orders.”
A broad grant of section 1292(a)(1) jurisdiction posited by such cases as D’Iorio and Kohn appears directly to contravene the admonition of the Supreme Court in Gardner and Switzerland Cheese. Kohn, however, relied upon a different line of Supreme Court precedent, the genesis of which was Smith v. Vulcan Iron Works, 165 U.S. 518, 525, 17 S.Ct. 407, 410, 41 L.Ed. 810 (1897). In Smith, the Supreme Court construed the predecessor of section 1292(a)(1) to authorize “according to its grammatical construction and natural meaning, an appeal to be taken from the whole of such interlocutory order or decree, and not from that part of it only which grants or continues an injunction.” Reliance upon Smith, however, was misplaced. In Smith, the Supreme Court went on to say that the intent of the provision in question was “not only to permit the defendant to obtain immediate relief from an injunction .. . but also to save both parties from the expense of further litigation, should the appellate court be of opinion that the plaintiff was not entitled to an injunction because his bill had no equity to support it." 165 U.S. at 525, 17 S.Ct. at 410 (emphasis added). Smith holds, therefore, that where appellate jurisdiction is based on section 1292(a) but it appears to the appellate court that there is no merit to the complaint whatever, the entire case will be dismissed. This holding is much narrower than the excerpt quoted in Kohn would appear to suggest.
N.L.R.B. v. Interstate Dress Carriers, Inc., 610 F.2d 99 (3d Cir. 1979), reflects more accurately the meaning of the Smith case. There, the district court denied a motion for a preliminary injunction and, in the same order, directed that discovery go forward. We decline to review the discovery order, concluding that, unless “subject matter jurisdiction is entirely lacking or the pleadings disclose no claim upon which relief could be granted . . . the discovery order is interlocutory and unreviewable.” 610 F.2d at 104.
The other circuits that have considered the issue appear to have taken the more restrictive view of section 1292(a)(1) that is reflected in such opinions as Interstate Dress Carriers and Gore, discussed supra. Both the Second and Seventh Circuit approaches deserve close examination. In Hurwitz v. Directors Guild of America, Inc., 364 F.2d 67, 70 (2d Cir.), cert. denied, 385 U.S. 971, 87 S.Ct. 508, 17 L.Ed.2d 435 (1966), Judge Lumbard — reflecting the Smith court rationale — noted that
[a]s a general rule, when an appeal is taken from the grant or denial of a preliminary injunction, the reviewing court will go no further into the merits than is necessary to decide the interlocutory appeal.... However, this rule is subject to a general exception — the appellate court may dismiss the complaint on the merits if its examination of the record upon an interlocutory appeal reveals that the case is entirely void of merit. . . . Such an exception serves the obvious interest of economy of litigation... .
The Second Circuit carved out another narrow exception to the general rule in Sanders v. Levy, 558 F.2d 636, 643 (2d Cir. 1976), adhered to on this point en banc, 558 F.2d 646, 647-48 (2d Cir. 1977), rev’d on other grounds sub nom. Oppenheimer Fund, Inc. v. Sanders, 437 U.S. 340, 98 S.Ct. 2380, 57 L.Ed.2d 253 (1978). There, the Court concluded that it could review an otherwise nonappealable class action determination because there was “sufficient overlap in the factors relevant” to the class action issue and the other, properly appealable, issues. See also Marcera v. Chinlund, 595 F.2d 1231, 1236 n.8 (2d Cir.) vacated on other grounds, sub nom. Lombard v. Marcera, 442 U.S. 915, 99 S.Ct. 2833, 61 L.Ed.2d 281 (1979). Judge Waterman, in State of New York v. Nuclear Regulatory Commission, 550 F.2d 745 (2d Cir. 1977), carefully delineated the rationale behind the Hurwitz and Sanders decisions. Declining to review the merits of the entire case after properly assuming jurisdiction under section 1292(a)(1), he concluded:
What Hurwitz and Sanders have in common, and what distinguishes them from the present case, is that in each of them the expanded review undertaken by the appellate court required no greater expenditure of effort by that court than if it had strictly confined its review to the interlocutory order which was independently appealable.
550 F.2d at 760 (emphasis added).
A similarly circumscribed approach was adopted by the Seventh Circuit in Jenkins v. Blue Cross Mutual Insurance, Inc., 522 F.2d 1235 (7th Cir. 1975), aff’d on rehearing, 538 F.2d 164 (7th Cir.), cert. denied, 429 U.S. 986, 97 S.Ct. 506, 50 L.Ed.2d 598 (1976). There, the plaintiff, a former employee of Blue Cross, charged her former employer with sex discrimination in violation of Title VII. The requested injunctive relief would have enjoined the defendants’ current employee evaluation and promotion practices. In refusing to grant the plaintiff’s motion to certify a class including all current employees of Blue Cross, the district court effectively precluded the requested injunctive relief: because the plaintiff was no longer employed, she could not demonstrate “irreparable harm” to herself resulting from continued use of the evaluation and promotion practices. On these facts, the Seventh Circuit held the class certification question appealable, concluding that “there can be no doubt that the district court’s earlier refusal to certify the suit as a class action directly controlled its subsequent decision on the requested preliminary injunction.” Id. at 1238 (emphasis added) (footnote omitted).
A fair reading of the relevant Supreme Court precedents, as well as the discussions of section 1292(a)(1) found in the decisions of the other circuits that have considered the issue, lead us to conclude that the broad grant of section 1292(a)(1) jurisdiction adopted in such cases as D’lorio and Kohn is incorrect. The Congress that drafted section 1292 set forth four exceptions — and only four — from the basic rule that interlocutory orders are not appealable. Mindful of the Supreme Court’s counsel in Gardner, supra, and Switzerland Cheese, supra, we decline to reach out and extend our jurisdiction absent further directives from Congress. Instead, we hold that a pendent class certification order is not appealable under section 1292(a)(1) unless the preliminary injunction issue cannot properly be decided without reference to the class certification question.
Our holding today reflects the carefully tailored reading of section 1292(a)(1) that has been mandated by the Supreme Court and advocated explicitly by the Second and Seventh Circuits. If the preliminary injunction issue appealable under section 1292(a)(1) cannot be resolved without reference to the otherwise nonappealable class certification issue — either because the latter issue directly controls disposition of the former, or because the issues are, in some other way, inextricably bound — then both issues must be addressed in order to resolve properly the section 1292(a)(1) preliminary injunction issue. In such a situation, the appellate court has no choice: any more limited review would deprive the appellant of his or her congressionally mandated right to a section 1292(a)(1) interlocutory appeal. If, on the other hand, the appellate court can dispose of the section 1292(a)(1) appeal without venturing into otherwise nonre-viewable matters, its jurisdiction should be limited accordingly.
A contrary rule would have serious and unfortunate consequences. For one thing, extending appellate jurisdiction over interlocutory orders not explicitly covered by section 1292(a) could disrupt the functioning of the district court by prematurely taking matters out of the district judge’s hands. An appellate court decision to assume jurisdiction over a class certification order, for example, which “may be altered or amended before the decision on the merits,” Fed.R.Civ.P. 23(c)(1), is — -in the absence of extraordinary circumstances — a usurpation of the district court’s role. In addition, any rule that encourages a broad range of appeals under section 1292(a)(1) invites abuse. Litigants desiring immediate appellate review could simply encumber their complaints or counterclaims with prayers for injunctive relief. Finally, and most importantly, the standard arguably suggested in D'Iorio and Kohn could effectively undermine the final decision rule. Once we begin reviewing a broad range of interlocutory orders, we defeat the narrow scope of section 1292(a) that was clearly intended by Congress.
C.
Turning to the present appeal, we conclude that the order denying the class certification is not appealable as a concomitant of the order denying preliminary injunctive relief. Under the standard that is inferrable from section 1292(a), a mere nexus between the two orders is not sufficient to justify a decision to assume jurisdiction. Thus, the fact that the definition of the term “indigency” was relevant to both issues is not enough, by itself, to warrant the extension of our jurisdiction. Unlike Jenkins v. Blue Cross Mutual Insurance, Inc., supra, this is not a case in which the order denying the class certification “directly controlled” the refusal to grant a preliminary injunction. As an appellate court, we can resolve the preliminary injunction issue without even a reference to the order denying class certification. Indeed, it is instructive to note that, in this case, the Magistrate disposed of the preliminary injunction issue in its entirety before addressing the motion for class certification. Appendix at 62. Additionally, as the appellees point out, “it is conceivable that preliminary injunc-tive relief could have been granted while class action status [was] denied and the same result desired by the inmates would have been achieved.” Brief for Appellees at 15. The two issues are separate and distinct; in no way can they be said to be “inextricably bound.”
IV.
We therefore hold (a) that the ruling of the district court denying the request for a preliminary injunction will be affirmed, and (b) that the class certification order is not reviewable under section 1292(a)(1) at this point in the litigation.
The matter will be remanded to the district court for action consistent with this opinion.
. Kerchner’s name was docketed as Kershner, but except for the caption we will use the correct spelling of his name in this opinion. See Ford Motor Credit Co. v. Milhollin, 444 U.S. 555, 555 n*. 100 S.Ct. 790, 790-91 n* 63 L.Ed.2d 22 (1980).
. While there is a claim that there was a failure to provide § 1983 forms for prisoners, the failure to provide enough § 1983 forms was found by the Magistrate to be nothing more than a “temporary short fall [which] resulted . .. [when] a check disclosed that there were only 5 sets of forms on hand. Gerber felt he had to limit the number of forms given to Ryan, until supplies could be replenished, when one considers that there are 850 men in the prison [sic] . . . Moreover, this court can take notice that many handwritten civil rights complaints, not on the required forms, are filed in this district.” Appendix at 60. We cannot conclude that these findings were clearly erroneous.
. It must be emphasized that this case comes to us as an appeal from the denial of a preliminary injunction. It does not arrive with a detailed record. No testimony has been taken, and the case was decided on the basis of sparse affidavits. What may be error on an appeal from a final order may not constitute error at the present posture of review. Continental Group Inc. v. Amoco Chemicals Corp., 614 F.2d 351, 357 (3d Cir. 1980).
. Section 1291 provides: “The courts of appeals shall have jurisdiction of appeals from all final decisions of the district courts ... except where a direct review may be had in the Supreme Court.” 28 U.S.C. § 1291 (1976).
. See note 7 infra & accompanying text.
. This issue was specifically reserved in Gardner v. Westinghouse Broadcasting Co., 437 U.S. 478, 479 n.3, 98 S.Ct. 2451, 2453 n.3, 57 L.Ed.2d 364 (1978).
. Section 1292(a) also extends appellate jurisdiction to interlocutory orders appointing receivers, or refusing orders to wind up receiver-ships or to take steps to accomplish the purposes thereof, such as directing sales or other disposals of property, 28 U.S.C. § 1292(a)(2); interlocutory decrees of such district courts or the judges thereof determining the rights and liabilities of the parties to admiralty cases in which appeals from final decrees are allowed, 28 U.S.C. § 1292(a)(3); and judgments in civil actions for patent infringement which are final except for accounting, 28 U.S.C. § 1292(a)(4).
Section 1292(b) permits a district judge to certify a question of law to the appellate court if the judge believes that “the order involves a controlling question of law as to which there is substantial ground for difference of opinion and that an immediate appeal from the order may materially advance the ultimate termination of the litigation.”
. See also Deckert v. Independence Shares Corp., 311 U.S. 282, 286-87, 61 S.Ct. 229, 232-233, 85 L.Ed. 189 (1940), in which the Supreme Court, citing Smith, held that the Court of Appeals “properly examined the interlocutory order denying the motions to dismiss, although generally it could consider such an order only on appeal from a final decision” because “ ‘[i]f insuperable objection to maintaining the bill clearly appears, it may be dismissed and the litigation terminated’ ” (quoting Meccano, Ltd. v. Wanamaker, 253 U.S. 136, 141, 40 S.Ct. 463, 465, 64 L.Ed. 822 (1920)).
. See also Loya v. Immigration and Naturalization Service, 583 F.2d 1110, 1113 (9th Cir. 1978) (footnote omitted), in which the court held that the order refusing to certify the class was not appealable under either § 1291, citing Coopers & Lybrand v. Livesay, 437 U.S. 463, 98 S.Ct. 2454, 57 L.Ed.2d 351 (1978), or § 1292(a)(1): “We need not decide now if we would adopt the Jenkins holding. Under its own terms it cannot apply to the present case. In Jenkins the failure to certify the class ‘directly controlled’ the later decision to refuse a preliminary injunction. In the instant case, the district court granted partial summary judgment denying injunctive relief for reasons independent of whether the suit was maintained individually or as a class action.”
. Similarly, if inquiry into the preliminary injunction issue reveals that the case has no merit and that judicial resources would be wasted were the case to continue, it would appear salutary to dismiss the action in its entirety. See Smith v. Vulcan Iron Works, supra; Hurwitz v. Directors Guild of America, Inc., supra. The present case does not raise this issue, however.
. This test has been adopted by at least one authority. See C. Wright, Law of Federal Courts § 102, at 513 (3d ed. 1976) (“[Rjeview quite properly extends to all matters inextricably bound up with the remedial decision and the court, if it sees fit, may consider and decide the merits of the case and may order dismissal of the action”). In contrast, the second edition of Professor Wright’s treatise read: “It is settled that an appeal from an order granting or refusing an injunction brings before the appellate court the entire order, not merely the propriety of injunctive relief, and that the appellate court may consider and decide the merits of the case and may order dismissal of the action.” C. Wright, Law of Federal Courts § 102, at 459 (2d ed. 1970). We can infer that the change in Professor Wright’s approach occurred in response to such cases as Sanders, supra, and Jenkins, supra.
. Our holding today in no way impairs the vitality of such cases as Latrobe Steel Co. v. United Steelworkers, 545 F.2d 1336 (3d Cir. 1976) and United States v. Spectro Foods Corp., 544 F.2d 1175 (3d Cir. 1976), in which we held that “an appellate court may consider the matter of a civil contempt in connection with an appeal from the underlying preliminary injunction.” Latrobe Steel, 545 F.2d at 1340.
. Of course, there may be an appeal at this stage in the litigation when the district court certifies such an appeal under § 1292(b). See note 7 supra.
