They can be! Note that a scholarly book is not just any old nonfiction title, but they can be a little harder to distinguish sometimes.
You are not actually expected to read entire books for research! Wait, keep reading, this is important!
Generally speaking, for most of the research you're doing at this lower-division undergrad level, you're reading to get information on your topic with enough context to not misrepresent anything. It is natural to not read a book cover-to-cover in this context.
That said, you need to use books that you reasonably have access to the content of. So you didn't read them, but you could have, and you aren't just going off the summary from the publisher. Good news! There's all kinds of library e-book collections that allow you to do just that for free -- and you can even "search inside" to skip around to the most interesting parts.
Search for the name of the piece you’re researching (if it’s a famous one) and/or the artist’s name to find related ebooks. Relevant subject terms include:
You can search the library catalog (below) with keyword, title, author, etc -- pretty much like using Amazon. (The catalog also finds most of our e-books, but it's still a good idea to search those collections directly.)
You are on a bit of a deadline, so you want to be sure you can get a book your want on time!
If you really want a book and don't have time to wait for it, call the library that has a copy, ask them to verify it's there, and they'll usually pull the book for you, just like placing a hold through the catalog. Then drive over to that library to get it -- but definitely call before committing to the drive!
