Cutter numbers are an alpha-numeric code for the author's last name. It does not have to be the entire last name, but usually 3-4 letters of it. This part of the call number further determines where the book is placed on the shelf. There are also geographic cutter numbers, but author is what you will see most frequently.
Here's an example for the book "Thought Patterns for a Successful Career" by Lou Tice
HF5381 - Subject (Business Career Development)
.T53 - Cutter for last nameTice
2006 - copyright year
