To locate the book, take note of the call number and location of the book displayed in the Online Public Access Catalog (OPAC).

There are 4 major locations - Medicine (Level 1), Allied Health (Level 2), Theses (Level 3), Periodicals (Level 3), and Multimedia (Level 4). Within each location are sublocations such as Reference, Filipiniana, General Circulation, and Reserve. Shelves are labeled as appropriate. Once you know the location of the book, proceed to that location. 

Next, take note of the call number. The library uses the Library of Congress Classification Scheme to organize the books on the shelves. First, read the first line alphabetically. Example, AB BD BF BX C CC CD. Next, read the second line as a whole number. Example, 5 10 11 13 25 37. The first two lines represent the subject of the book.

The third line is a combination of letters and numbers that represent the author or title of the book. Read the letters alphabetically then the numbers as a decimal number.  Example, B42 B48 B761 C11 C25. The last line corresponds to the date of publication.

Each shelf row is labeled with the class number of the first book in the row. This will help you easily navigate within each row of the shelves. 

QUICK TIP: The first 2 lines correspond to the subject of the book thus, expect to find books with similar topics shelved together.
