The First Outline of the Library of Congress Classification is Published

Date(s)
1901

The first schedule (Class E-F = American History & Geography) of the Library of Congress Classification (LCC) was published in 1901 by Charles Martel and J.C.M. Hanson. Whereas the Dewey Decimal Classification System (1876) was devised as a means to organize all knowledge by one Mr. Melvil Dewey, the LCC was created to describe the specific holdings of the Library of Congress. Each class schedule (for example: Class Z = Bibliography & Library Science) was created by groups of subject experts.
