Library Cataloging
After reading the paper Hierarchical Gaps and Subject Authority Control Processing: an Assessment I'm not so sure this is a good way to go, at least for us. The paper describes how they added LCSH records for all broader terms needed when they added a new subject term. For example, when the term Venturia inaequalis was needed they also added Venturia, Venturiaceae, Pleosporales, Loculaoscomycetes and Ascomycedtes.In our catalog these would all appear as blind references, a user would get no hits. A user who followed the list of broader terms could go far before getting a hit. He could not move to more specific terms, narrower terms are rarely used in LC records.Part of the problem is in our OPAC. There are none, I know of, that display a subject tree based on the LCSH's. This structure is useful to some of our users. Yahoo has this structure and it gets used. The structure should also be able to display the number of items at all lower levels. For example, a search on Ascomycedtes should show that there was 1 item with a more specific heading as well as the fact there were none at that level. Should it show how many were higher in the tree? For some headings, it would be a google-like number, too large to be useful. For United States--History--Civil War, 1860-1865 the number of items in United States--History and United States would be useless. However, this is speculation, the system does not exist.Personally, I like being able to move up and down a tree structure. I'd like to see this kind of access to our classification schemes also. But until our catalog offers that functionality or I see research showing adding those missing headings in the hierarchy does improve searching I'll not be adding them.
