How to Read Call Numbers
Call numbers are simple once you get the hang of it!
First, when you look at a call number, you will read it alphabetically: AB comes before BB, which comes before CB.
Then, you read it numerically: BB20 comes before BB100, which comes before BB200
Remember: even though 20 starts with a 2, it is still a smaller number than 100!
So, if we put CB395, AB100, CB40, and BB600 in order, it looks like: AB100, BB600, CB40, CB395
