Does there exist any digital copy of the original article (or a transcript) K. Levenberg, *A method for the solution of certain problems in least-squares*, Quart. Appl. Math. 2 (1944): 164-168?


It is (obviously!) cited in numerous works, but the paper itself appears to have completely vanished. There seems to be not even any publisher, library, etc. proposing to buy a hard copy or anything alike. Apart from the citations all over the places, the paper has ceased to exist?!


(The question has also been posted on [Mathematics SE](https://math.stackexchange.com/questions/897244/levenbergs-original-article-a-method-for-the-solution-of-certain-problems-in-l))



Levenberg's original article "A method for the solution of certain problems in least squares"
This [link](https://doi.org/10.1090/qam/10666) might be better. The paper is now open access and the pdf is searchable.
