You will need to use two pieces of information to locate materials in the library:

1. Location Code
2. Call Number

The catalogue record for an item indicates both its location code and call number.

Location Codes

A location code is a section of the library where items are shelved.  Location codes indicate the floor an item is on, and what area on that floor.  Examples:

  • SER for serials/journals
  • DDV for the government documents main collection
  • MFL for the microfilm collection

See the complete list of our location codes.

Call Numbers

Most materials in our collection use Library of Congress call numbers. These use an alpha-numeric system that shelves books by subject. All books on the same subject will shelve together regardless of who wrote it, or where it was published. 

Government documents use the CODOC numbering system. This system uses jurisdiction as the main way of organizing items. This means that all the documents coming out of one government department will be shelved together, regardless of the subject matter.

Additional Tips

  • Is the item checked out?  Check the catalogue record status information.
  • Are you in the right area?  Check the catalogue record for location information.
  • Are you looking at the right place on the shelf?  See the call number guides above.  In case the item was mis-shelved, scan the shelves in the vicinity.
  • Is this a very new item?  Go to the New Books section located across from the Research Help Desk.

If you still cannot find it, contact the Library Services Desk.
