Biological Sciences: Books and Journals

Explaining the Library of Congress Classification System

What is a call number and how do I use it?

When you enter the details of the item that you want on the catalogue it will display a call number or code that tells you where the item is shelved.

The call number will usually look something like these examples:

TK 2380.45 GAR 

306.47 GEL 

B OCEAN (Physical) Kna 

Although the codes look different, they work in much the same way: the combinations of letters and numbers gives a location based on the subject content of the item. The items are arranged on the shelves using the call numbers.

The library floor plan will show you where items with particular call numbers are stored

Books and Journals

stack of booksLooking for a book or a journal article?   

Go to the library catalogue  and search by title, author, or keywords.

Is the book out on loan or at another site? - Place a hold

Is the book not held by the library at all? - Use the Inter library loan service to borrow it from another library

Recommend a book? - Contact your Academic Engagement Librarian if you would like to recommend a book we should buy for the library.
