LC* Classification*Library of Congress

The Library of Congress System• “Libraries use classification systems to organize the books on the

shelves. A classification system uses letters and/or numbers (call numbers) to arrange the books so that books on the same topic are together. This arrangement results in "serendipitous browsing:" you find one book in the catalog, go to the shelf, and an even better book is sitting right next to it.”

- University of Georgia Libraries

What SU Libraries Use:• We use the Library of Congress classification system• Public libraries tend to use Dewey Decimal• It’s just a different way of keeping books of similar/related subjects

together• The books are shelved by call number which is a series of numbers

and letters that indicate where the book should go

Parts of a Call Number• On the spine of the book, you’ll find a sticker with numbers and letters. • There can be more or fewer lines than shown here:

In Bird Library:• Call numbers A – DX are on the 2nd floor• Call numbers E – HJ are on the 3rd floor• Call numbers HM – NA are on the 4th floor• Call numbers NB – PZ are on the 5th floor• Anything Q – Z is at Carnegie• This doesn’t include what is stored offsite or in another location• Many bound journals• Special collections/rare books• Architecture Reading Room• Law Library• MLK Library

general direction, try to see if they need more assistance• Reference librarians and Learning Commons can help students find exactly
