Course Reserves
Some instructors will put textbooks on reserve at the University Library to make course materials accessible to students. You can search course reserves for your textbooks by instructor, course number, or book title.
Quick tip: Many textbooks on reserve can only be checked out for two hours due to high demand. If you're relying on course reserves to do your reading, you may want to scan the chapters you need so that you can read them later without worrying about the time limit.
Online Textbooks
Search for textbooks & ebooks in the library catalog using OneSearch by applying the search filter "Available Online at CSUN"

CSU+
If CSUN doesn't have your textbook, you may be able to borrow it for 30-60 days from another CSU campus. Just make sure to set the dropdown in OneSearch to "All CSU Libraries".
