Library of Congress (LC) Call Numbers

Call Numbers Simplified

The Library of Congress Classification System uses a combination of letters and numbers to arrange materials on library shelves by subject.

On the label, call numbers are read in alpha-numeric order line by line from top to bottom.

sample catalog results listThe library's catalog provides an inventory of all the items available at the library.

You can use the catalog to search for specific items by their title or author, or you can search for items on a specific topic using keywords.

From the results list, you can click on an entry to view an item's availability, location, and call number.

If an item is currently checked out by someone else, you can even place a hold on it to be notified when it is available.



Catalog Search Tips

The catalog can be used to search for books and other materials that are available at the NSU libraries. 

  • If you do not find any results, then check your spelling or the fields you searched in.  Selecting different fields will produce different results.
  • If you find too many results, go back and limit your search. Sometimes a search needs to be modified with additional search words, searching only a specific field, adding date limitations, or type of materials.  You can search by keyword, author, title, etc.
  • If you find too few results, go back and expand your search. Consider using synonyms for your search words or try to use professional language or terminology.
