In order to find books, journal titles, videos, government documents and other materials held in the University of Maine System you will need to consult URSUS, the online catalog. Because journal article citations are not individually included in URSUS, you will need to use a discipline-specific index to find this information (see Resources by Subject).
If you do not know the exact subject heading describing the topic you need, try doing a keyword search using other word/s related to that topic and then click on the subject heading links found within the relevant records to find additional, useful resources.
The Library of Congress provides a breakdown of the call number classification scheme. To find a listing of psychology call numbers click on any of the subcategories to see more detail.
To obtain materials not located at USM, but still within URSUS, you will need to click on the Request button on the URSUS screen and enter your name and barcode number (found under the barcode on your USM Card, which begins with 25022....). Your barcode will need to be activated at the Circulation Desk.
If the item is not available through the University of Maine System (URSUS) or MaineCat you can request it via Interlibrary Loan (ILLiad).
