Interdisciplinary Library of Congress Subject HeadingsThis is a featured page

You know how when you have a giant reference book, and you’re looking for something particular, you flip to the index? And generally what you’re looking for, if the book contains it at all, is going to be found under one of a few index words. LoC Subject Headings are like one giant index for all materials in a library’s catalogue. They make it so people can find what they’re looking for without knowing pesky details like title or author.

More specifically, taken as a whole, Library of Congress Subject Headings (LCSH) comprise a tool created by the United States Library of Congress. The tool, which physically results in a thesaurus of controlled vocabulary[1] colloquially known as 'The Big Red Books' (of which there are currently five), serves two purposes. Firstly, it is an organization tool for professionals in libraries and other information institutions to use as established framework by which to catalogue materials. Secondly, it is a search tool for users of said institutions, as an alternative to searches by author(s), or title, among others. LCSHs are applied to every item within a library’s collection and they are searchable online at the Library of Congress Authorities.

[1] Controlled vocabulary schemes mandate the uses of predefined, authorized terms, in this case Library of Congress Subject Headings, that have been preselected by the designer of the controlled vocabulary as opposed to natural language vocabularies where there is no restriction on the vocabulary that can be used.

It is important to note the structure of LCSHs because it can enhance your results. Since 2001, the Library of Congress has been working to standardize LCSHs in the arts. The new pattern is called free-floating subdivisions and iswritten like this: Drawing, French--France--Paris--20th century.[2] In this example, "France" is a narrower term for "Drawing, French." "France" is also a broader term for "Paris." The number of search results are increased when going from a specific, narrower term to a broader one. Likewise, if the search yields too many results, a narrower term may be more useful.

Interdisciplinary research and collaboration, especially those between the arts and the sciences, is often encouraged by academic institutions and funding sources. On the following pages, you will find scenarios describing sample collaborative projects, and a list of applicable LCSHs to the given situation. It is hoped that this resource will encourage you to consider the vast opportunitites outside of your immediate area of study, and the exciting ways your expertise can be utilized.
