Do you ever teach others how to use call numbers? Does it go something like this?
First, remember to place them in order alphabetically. When a call number begins with one letter, it comes before another that has two letters: N before NA, for example. Then, look at the numbers. Count up from the number one: 1, 2, 3, 4, 5, 45, 100, 101, 789, 1001, etc. Third, notice the decimal .5 comes before .52, which also precedes .6, since it is a decimal.
- N100.C45 comes before NA99.A33
- N100.C45 comes before N100.5A32
- N100.C45 comes before N100.C5

In looking for the links to the Library of Congress, I discovered a very brief message from Clint Eastwood, America's tough guy. He encourages the viewer, you and me, to make our day by reading a book: Clint Eastwood video. We are talking about finding books in the catalog and on the shelves today in the ACAD 1199 class I am teaching. This video seems like an appropriate one to start the class.
It seems like a good idea to teach about keyword Boolean searching, subject heading searching, and understanding call numbers. Ideally, students will leave the class more confident searching the catalog and finding books on the shelves.
If you teach library instruction classes, what have you done to instruct students in searching your library's catalog?
