They deposit PDFs because PDFs are citable.(May be they delete electronic versions after publication, too.)It seems that DASH has checked the publisher's policies and made accessible 3 of the 100 eprints. In one case I cannot explain why the eprint is free, in another ROMEO says that OUP allows using the publisher's PDF.Please note that DASH has no eprint button. I have argued  several times against it:?s=eprint+button(I do not know if Harvard affiliated users can access the closed eprints. If not one can wait until Professor Knoll is 70 years dead and the copyright is expired. If they can this is only an advantage of the "happy few" at Harvard.)(iii) It is not helpful for users that DASH doesn't gives a hint if the link to the publisher's version leads to free content.(iv) Don't trust in DASH! Scholars should always search for free versions in Google Scholar and if not found there in the Google websearch.One cannot expect that DASH is so courageous to link to free versions in the web (these could be illegal ones).(v) It is not possible easily to measure the effect of Harvard's OA policy if one cannot filter no-free eprints in DASH.Update: http://archiv.twoday.net/stories/6250326 Source: http://www.eps.harvard.edu/people/faculty/knoll/Knoll_on_Mars.jpg
