The call number alone is not enough to find a book. You also need to note the location. The Libraries use the same call number system across multiple collections in multiple libraries.

Once you know the location, the Libraries' basic call number system is easy to use. Let's say that you wanted to find this book:

Richter 4th Flr Stacks
QE83 .G7413 2003 

Once you get to the fourth floor of Richter, look for the Q's. They will go Q, QA, QB, etc. Find the QE's.

Within the QE's, they will go 1,2,3,4,5, etc. Find the 83's.

Within the QE 83's, they will go .A, .B, .C, etc. Find the .G's.

Within the QE 83 .G's, you are now dealing with decimal numbers. .G2 will come after .G14. Between .G7 and .G8, you will find .G7413.

Once you get that far, you should have no trouble finding the book. If you cannot find it, go to the Access Services desk on the first floor and ask for help.
