How to cite an old paper? My first article was accepted with minor revisions, one of them being the correction of a citation. This citation points to the first time the method I am improving was proposed, which was 1962.

Here is a link to the Paper : http://www-isl.stanford.edu/~widrow/papers/c1961generalizationand.pdf 

It is on the Stanford online library. I found this paper cited multiple times in the following way:


  B. Widrow, ``Generalization and Information Storage in Networks of
  Adaline `Neurons','' in Self-Organizing Systems, symposium
  proceedings, M.C. Yovitz, G.T. Jacobi, and G. Goldstein, eds.,
  pp.435-461, Spartan Books, Washington, DC, 1962.


So I used it, but the reviewers are still asking me for a revision as they deem it to be incorrect. So my 

Question:

How to cite this paper in a Periodica Polytechnica journal ?



EDIT 1 :

Thank you for your help, They didn't point to a particular correction, here is a print screen of their comment :
First of all, this doesn't look like a reviewer's comment, but rather like a copy-editor's comment. And if I interpret the comment correctly, they just want a note that indicates when the resource was last accessed for all online resources. So you only have to add "(Accessed 10 January 2020)" after the URL.
This is completely unrelated to the age of the paper.
