WorldCat at UMass Boston

Locating a Book

The catalog record for a book lists a location; usually in the Main Stacks -- Main Stacks are on the 8th & 9th floors of the library.

The catalog record also gives a call number, a collection of letters and number that uniquely identifies its location in the library. Healey Library uses the U.S. Library of Congress Classification (LCC) system to assign call numbers.

A typical call number looks like this: QD934.C49C7. All the books in the library are arranged on the shelves by their call numbers. The initial letters in the call number indicate which floor to look on, and the rest will help you narrow down the exact shelf location to find the book.

  • A-NC: Floor 8
  • ND-Z: Floor 9
