Abstract
The Library of Congress Subject Headings system, and the National Library of Medicine's Medical Subject Headings thesaurus have been mapped. The mapping data have been entered into 7XX fields of USMARC authority records. The data continue to be updated as subject headings are added, deleted, or changed in information languages. lt is planned to distribute the mapping data in both MARC and non-MARC formats to libraries, vendors, bibliographic utilities and other developers of information systems.

"1. The LCSH/MeSH Mapping Project The problems that are created when two or more information languages reside in the same system have been widely studied. Most of the solutions to these problems involve the integration or harmonization of the languages (Maniez, 1997). One method for integrating multiple information languages in library catalogues and other databases is to map terms in each language to corresponding terms in the other languages (Mandel, 1987). This is the approach taken by the Northwestem University libraries in a project to map the Library of Congress Subject Heading (LCSH) system to the National Library of Medicine's Medical Subject Headings (MeSH) thesaurus. The mapping project was begun in 1990 and continues at the present time. The project was divided into two phases: (1) a retrospective phase that mapped LCSH as it existed an April 14, 1990 and the 1989 MeSH; and (2) an ongoing phase during which the mapping data have been updated to take into account additions, deletions and changes to the two information languages."
