Library of Congress Explanation


A QUICK DEFINITION OF LIBRARY OF CONGRESS CLASSIFICATION IS THAT: It's an alphanumeric system of classification used by the Library of Congress that describes books via letters and numbers that correspond to the subject and title/author information. Its the same system used by most academic libraries.

Phew, but what does that really mean?
It bascially means that we arrange books by the call number, which acts like the street address for the book.. Once you get that call number you can easily find the book and pull it off the shelf. In addition, since the books in the Library of Congress Classification scheme are organized by subject. Once you have the call number of the book you are looking for, you can easily find more on that same topic on the same set of shelves.

Take this record from EUREKA as an example:

The call number is F 128.5 .G25

F stands for United States Local History
128.5 stands for New York
.G25 represents the authors last name
