[greenstone-devel] Hierarchical AZList classifier

Subject	[greenstone-devel] Hierarchical AZList classifier
I have a collection with about 300,000 bib records from marcxml. I have modifies the MARCXML plugin for this collection to add vertical bars("\|") between each of the subfields in the MARC 650 field which I map to Subject. This gives me the ability to use the Hierarchy classifier on Subject. As there are so many records, the hierarchy list goes on forever. I would like to have an A-Z list for the top level of the hierarchy and then display the hierarchy when I select a particular top level subject. I haven't seen any classifier that can do this. Is it possible? has anyone written this type of classifier? Thanks in advance. -- Arthur Belanger Medical Library System Manager ITS Academic Media & Technology Yale University PO Box 208065 New Haven, CT 06520-8065 (203) 785-6928 (203) 737-2859, fax mailto:Arthur.Belanger@Yale.Edu http://www.yale.edu/its/about/amt http://info.med.yale.edu/library
