What is it about?

Class G provides granular classification for most cartographic materials through a well-established and expanded Cuttering system, maps of imaginary places are classified under G9930 which has no formal expansion. With the creation of a collection of imaginary maps at the Texas A&M University Libraries, the lack of expansion under G9930 created access and filing complications. This case study describes the problem that growing a collection under the unexpanded classification system posed and the solution that was found through the creation of an in-house expansion for G9930.

Why is it important?

This article introduces a locally developed expansion to LoC Class G for maps of imaginary and fictional locations, walking readers through how the expansion was developed and implemented. For libraries that choose to expand their collections of imaginary maps, the locally developed expansion could be implemented in their collection.


The work that this article is written about was a necessary classification expansion, I was (and continue) to grow our imaginary map collection and faced difficulties with finding and filing the maps due to the lack specification in the LoC Class G. Before creating my locally implemented expansion the maps essentially had the same call number!
