Find Books, eBooks, and More

Search Books, eBooks, and More in the OCCC Library Catalog

Use the OCCC Library Catalog to identify OCCC books, eBooks, and more on your topic. Here are some tips for searching in the OCCC Library Catalog: 

  • Keywords: Use keywords, not sentences like you may do in Google (example: wound care NOT how do you treat wounds)
  • Multiple Keywords: You may use multiple keywords when doing a search. Start with one and add others as needed to narrow your search (example: stroke and rehabilitation)
  • Publication Date: Be aware of the publication date. After your initial search, update the publication date to get rid of older titles in your results list.
  • Material Type: If you are looking for a specific material format, select from the "Material Type" list under "Limit Search Results" on the left.

LC Classification for Business

All items in a library are marked with some sort of call number so that you know where you can find it. The OCCC Library uses the Library of Congress, or LC, call number system. Browsing the shelves in a library can be a great way to find interesting books, as well as familiarize yourself with the collection and layout. If you want to browse the book shelves in the business subject areas, the call number areas listed below will help get you started. All items on the 2nd floor of the OCCC Library can be checked out and taken home, but don't forget to take a look at the Reference Collection as well. Although Reference items must stay in the Library, there are some great resources in that area you won't want to miss. Reference items are located on the 1st floor of the Library.
