to identify a specific book and its call number use the call number to locate that book (or video, etc) on the shelf


  • Looking for an author? Try family name, first name (Steinbeck, John).
  • Getting too many irrelevant titles? Click "Subject" instead of hitting "Enter."
  • Need a video? Click "Power Search" at upper right of screen, scroll down to "Location" and highlight "AV."

Notice the location - most often it is "second floor."

For more tips and better results, check your search strategy.

Finally, be sure to write down the call number for books you want to look at!

Understanding call numbers

Each book has a unique call number. The call number is a book's "address." Use it to locate a book on the shelves. Books as well as videos, DVDs and other items in this Library are organized by subject using the system used by most college libraries - the Library of Congress classification. Books of a similar subject have similar call numbers and sit together on the shelves.

Call numbers begin with one or two letters. You will see them in 2 different formats:

  • Listed in the online computer catalog: B 74 .M67
  • On the spine label of a book: B74 .M67

Read and compare call numbers line by line.

Items are shelved alphabetically - left to right - by the top letter or letters in the call number. For example, all the Bs come before a BF item.

  • B 74 .M67
  • B 105 .T266
  • B 105 .T54
  • BF 76.7 .P83

Then all call numbers with the same top letter are sorted by the number below. In the example, B74 comes before B105

All materials that have the same beginning letter and number are arranged alphabetically by the letter after the decimal point, then by the decimal number. Hint: Think of .T266 as .266 - a number smaller than zero. For this reason, B105.T266 comes before B105.T54.

There may be a final number, the date of publication. Chronological order: 1995 comes before 2002.

Using Reference Tools to Find Background Info

Reference tools can be printed books or online databases. Each is organized so you can easily "refer" to them for background information, definitions, facts or statistics.

Use a library reference collection to start your research or to quickly find facts to support your argument. Reference tools provide:

  • background information
  • an overview of a topic
  • quick answers to questions
