GEM Subject is a subject taxonomy created and maintained as part
of the Gateway to
Educational Materials project. It is relatively broad
and shallow, with 238 classifications, and so may be easier to navigate.
LC Classification (AKA LCC) is a subject taxonomy created and maintained by the Library of Congress. It is very fine-grained and very deep, with more than 430,000 classifications, and so provides for extremely accurate and specific categorization of resources.
