“Classification” is one of those words that librarians say a lot but don’t really explain. So, what does it mean?
According to Arlene Taylor in the classic library and information science textbook the Organization of Information, classification means categorizing. It is primarily associated with putting markers on “physical information packages.” Like books.
Classification theory seems esoteric but actually shows up in all sorts of mundane ways. For example, when you walk into a bookstore, what does it mean that African-American or Gay and Lesbian literature are not part of the regular Fiction/Literature section? Who made that decision? Does it have implications for how you, the customer, approach the books in those sections?
St. Mark’s Library uses the following classification systems (in alphabetical order):
Early English Theology (EET)
Library of Congress (LC)
The third floor of the library holds the non-rare Dewey, Liturgy, and the end of the LC collections. Dewey 000-199 and 300-999 are packed but did you know that this actually means something concrete?
You might have noticed that the numbers above skip the 200s. We haven’t packed those yet b/c the 200s are about…Religion! We are packing the least used collections first and that does not include the Dewey 200s.
Here are the 9 remaining classes for Dewey that are now part of the sea of books on the 4th floor:
- 000 – Computer science, information, and general works
100 – Philosophy and psychology
300 – Social sciences
400 – Language
500 – Science
600 – Technology
700 – Arts and recreation
800 – Literature
900 – History and geography
More on classification tomorrow.
