Remember to get a library card if you can.
Use the Libby app with your library card for free audio or ebooks. Libraries typically offer other online resources too, it depends on your library but mine offers Kanopy which allows you to watch 10 movies a month, from blockbusters to smaller indie movies. We also offer Creativebug which is like a smaller version of skillshare for art/craft tutorials, and we had The Great Courses for a while which was art/history/science courses.
All of these are free with your card and your library probably has a lot of cool stuff you might not know about if you haven't checked recently.
For physical books: libraries (typically) have an innerlibrary loan system so even if your llibrary doesn't have a book, ask at the front desk.
If there's no way to get a book at your library, buy it off thriftbooks instead of Amazon.
