What is a call number?

Knowing an item's call number will help you find where the item is located in the library.

  • MiraCosta College Library uses the Library of Congress Classification System (whereas public libraries use the Dewey Decimal System.)
  • A Library of Congress call number contains a combination of letters and numbers, and typically ends with a four-digit year. For example: QL737.P2 C35 2011.
  • To find the call number for an item in OneSearch go to the results page under the title of the item. Keep in mind that only physical items, not electronic ones, will have call numbers.

What if I don't see a call number?

  • eBooks or any other type of electronic material may not always have a call number because they are not located physically in the stacks (bookshelves).  Instead you will be directed to the database that hosts the eBook. Use the Available Online link in OneSearch.
