Ask HN: How do you find free academic/scientific material?
5 comments
Sci-Hub, Researchgate, and Anna's Archive. I get the feeling that there's some system admins with peglegs and eyepatches, however.
https://arxiv.org (many fields) or https://eprint.iacr.org (cryptography)
If you haven't already, check out Kagi search with the "Academic" lens.
The shadow libraries are full of material like this.
scholar.google.com
When I need to learn about a new topic, I usually search for scientific articles. A few years ago, I discovered that I often got good results by searching for "KEYWORD PDF," as this led to static PDF files that aren't easily changed. Very often, they are written by academics or produced by government agencies.
Lately, however, I've gotten the feeling that the results more and more often lead to "zombie sites" that just redirect to ads and other junk.
