Our method of design for the 202 database involves the use of subject headings and subdivisions to combine a number of different topics. These combinations can be in no more than two terms: a heading and subheading. All terms come from the controlled vocabulary

Names of systems mentioned in this database refer to methods of information retrieval, and can either be a heading, if it is the topic of the article, or a subheading, if it refers to a topic presented in the article

Similar to the LCSH rules on geographic subdivision, topical subject headings can be further delineated by geographic subheadings, or geographic headings may be linked to a topic subheading. A geographic term can only be in the heading of the precoordinate term if it is also the subject (topic) of the article.

· Geography can either be a heading or a subheading
