The McClay Library uses the Library of Congress classification system to organize its books.  This system uses letters to indicate the broad subject area and then numbers for more specific topics.  

On each floor of the McClay Library (beside the floor plan) you’ll find a list of the subjects covered on that floor and their letter codes.  Please ask at the enquiry desk if you need help finding books.

Copies of books which appear on reading lists may also be found in the Short Loan collection on the Ground Floor. 

The books in Short Loan follow the same lettering system as those in the rest of the library.

Please note Medical and Nursing books are mostly held in the Biomedical and Medical libraries.
