As a student, you may have access to great resources through your school’s library (definitely check there first, especially for papers). If not, a lot of textbooks, papers, and resources can be found online for free. Here are some websites to check.*

For peer-reviewed/academic papers, also consider contacting the lead author if you’re unable to access a paper you’re interested in.

*Note that downloading from the web does sometimes carry risks. Don’t click on any pop-ups or links with your PDF download should they appear.
