This database is designed for students in the SLIS who have taken LIBR202 for their continued use during their program. The students will use this database to further their knowledge of information retrieval. Students will be conducting formalized queries. At this level the students are able to articulate the problem clearly.

The types of queries the students will pose will be mainly that of topics and methods of information retrieval. The articles were indexed generously, due to the many ways the student will be researching. The facets of the articles that need to be indexed are terms that are synonymous with information retrieval and the aspects of information retrieval.

Subject Headings Rules.

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 of ERIC descriptors. Terms can be strung together according to the following rules:.

The Heading will always be a topic.

The heading of the precoordinate term will always contain a topic of the article.

Topics can be subheadings.

Subheadings can also contain topical descriptors in relation to the topic described by the heading if they provide further classification on the field.

A Heading can also be a subheading.

Once designated as a heading, an ERIC descriptor can also be utilized as a sub-heading.

Form will always be a subheading, not a heading.

The method of presentation of the information, and the way of gathering it, (form) will always be listed as a subheading, and cannot be the main topic of the article.

System names can either be a heading or a subheading.

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.
