Don't let a call number overwhelm you! Approach the call number one line at a time, from top to bottom, as you look for the book.

1. Look at the first line: PS3552
   • Go to the correct floor. This call number begins with the letter P, so it's on the fourth floor.
   • Find the section where the first letter starts-- P
   • Then find the section where the letter combination starts-- PS
   • Find the number after the letters-- 3552
2. Look at the second line: .A473
   • Find the letter-- A
   • Find the decimal number-- .473
3. Look at the third line (if there is one): S2
   • Find the letter-- S
   • Find the decimal number-- .2
4. Look at the last line (if there is one). Find the date: 1992
