Columbia's Hierarchical Interface to LC Classification (HILCC) uses the LC Classification numbers provided in standard catalog records to generate a structured menuing system and and A-Z topical list for subject access on the web.  The HILCC call number map — jointly developed and maintained by the Libraries Digital Program Division and cataloging and reference staff — links each LC classification range with entry vocabulary in a three-or 4-level subject tree, for example:

LC Range: GN 301.0000 - GN 674.9990
Maps to: Social Sciences -- Anthropology -- Ethnology
