I have a bunch of PDF files which are articles downloaded from various Journal websites. The problem is, some of these PDF files are duplicates of one another. However, if I run a basic duplicate file finder, they won't show up, because journals have the (somewhat annoying) habit of putting a cover page in the PDF before the actual article. In other words, if I have two copies of article "X" by author Y, one downloaded from site A and the other site B, they aren't exact duplicates because one has cover page from A and the other has (different) cover page from B. So my question is:
Is it possible to check if two PDF files are duplicates,ignoring the first page?
Of course, this doesn't solve all my problems, since some journal websites don't put a cover page! So the best possible question would be:
Is it possible to check if two PDF files are duplicates,where one (or both) might have a cover page?
