So I am planning to release something soon and would like to share the handful of copyrighted papers that have inspired it, which were all obtained publicly on the internet.<p>Should I find canonical URLs and link, or would it be fine to have a directory with the PDFs for easier reference?
You have two options:<p>* DOI Numbers, which uniquely identify scientific papers<p>* "Paper style" citations, with Authors, Title, publishing Venue and date. This is enough for any interested reader to find the sources<p>I would not recommend hosting copyrighted material in a personal repository.
