Library of Congress -- Classification Scheme

Remember the Dewey Decimal System from high school or the public library?

Well, academic libraries at colleges and universities in the United States use a different call number system called 'Library of Congress Classification Scheme.'  Used by -- you guessed it! -- the Library of Congress in Washington, DC, this system creates unique text/object identifiers using a letter-number combination. Subjects are affiliated with a specific letter; if you refer to the image below, the letter 'D' is associated with World History.

For example, if you search for a text about Great Britain you will likely find it in the DA section of the library:

DA645 .R58 -- The Place-Names of Roman Britain
