Reading Call Numbers: What does the call number mean?

Reading the call number

Remember that Library of Congress Classification arranges materials by subjects. 

Description: http://lgimages.s3.amazonaws.com/data/imagemanager/28467/callnumberonly.pngThe first two lines describe the subject of the book

E745 = Military History

 

 

This line represents the person who is the subject for this book.

.M3 = MacArthur, Douglas

 

This line represents the last name of the author

.M27 =  Manchester, William

 

This is the year the book was published.

 

 

 

Why is this important?

Because books are classified by subject, you can often find several helpful books on the same shelf or nearby.

Since Library of Congress Classification arranges materials by subjects, knowing the letter(s) for your subject area gives you a place to start browsing the shelves.  Which letters represent your subject?  View the Library of Congress Classification Table.
