LB1050: Educational Psychology

RC:430-570: Psychiatry

We arrange every book on the shelves in the library by subject.  Like other academic libraries, we use the Library of Congress Classification System to assign call numbers to our materials so that materials on similar topics are next to each other on the shelves and patrons and staff can easily find what they need. 

You need to know a book's call number in order to get it off the shelf in the library. CSU, Los Angeles has created a guide that provides a useful introduction to the organizational scheme: 

Understanding Call Numbers 

Encyclopedias, dictionaries and other reference materials also follow the Library of Congress Classification System and can be found in the reference section on the Main Level of the Hammermill Library.

Placing a Hold on a Book

You can place a hold on an item that is currently checked out; when it is returned, you will be notified by email.

You can also place a hold on an that's located at the North East Campus' Ridge library and it will be sent to the Hammermill Library for you.

You can also place a hold from home on an item on Hammermill Library's shelf so it doesn't get checked out by anyone else before you get to the library.

To place a hold, find the book in the catalog and click on "Place hold​." You will be prompted to log in with your name and password and from there you can request that the book be sent to whichever campus library you need.
