Today is National Library Workers' Day, which recognizes the unique contributions that library workers make to help people find the information they need for learning, working and recreation.

One of the ways libraries have been helping organize information since 1876 is through the Dewey Decimal Classification, broken down into the following classes:

000 - Computer science/information/general works
100 - Philosophy/psychology
200 - Religion
300 - Social sciences
400 - Language
500 - Pure Science
600 - Technology
700 - Arts/recreation
800 - Literature
900 - History/geography
