Is your book from an Academic / Scholarly source?
Look at the publisher of the book, and then see if you can find it listed on AAUP list linked below. Note - there *are* some publishers that are scholarly that won't appear on this list. Two common ones are Brill and Routledge. If you think you've found a high quality scholarly book that you would like to use, you can also ask your professor or the librarian to help assess if your book will work.
