What exactly is a call number anyway?
A call number is the unique number given to each book in the library. Call numbers are like addresses, they tell you where a book will be located in the library.
Why should I know how to read one?
If you understand how to read a call number, it will be a lot easier for you to find books in the library.

A call number that you find in IUCAT (the online library catalog) will look like this:
CT105 .K55 1981
And that same call number will look like this on the spine of the book:
So, here's how you read a call number on the spine of a book:
CT --Read it alphabetically (A, B, C, CT, D, E, F, G, H, HA, HQ, etc.)
105 --Read it numerically (1, 10, 100, 100.5, 105, 1005.10, etc.)
.K55 --Read alphabetically and then decimally (.A23, .A233, .A33, .B4555, .B50, etc.)
1981 --The final line is a date.
And here is how this book would be placed on the shelf:
