Reference books should only be used for an overview, and not as one of your major sources. Because reference book articles are short, you are not going to find the level of detail required to write a successful paper.
Circulating books offers more specific information on one major subject with lots of details in its further subdivision. You may also find lots of supporting materials via facts, personal experience or survey as well as possible some statistics. It takes you to a deeper level of research.

Reference sources are also available in database form through the library. These sources are available 24/7!
Q. Dear librarian, After I searched the NOBLE Catalog system, I found one of the items I like to read having a call number like this: S863 G16F, what does it mean and where I can find it?
A. This prefix S means this item is in Spanish language. 863 means it is a book about Latin American Literature. To get a copy of that book, you will need to request that item from My Account. The books in Spanish are stored in the stacks in the attic. The librarians will help you get that copy after receiving your request.
