The Library of Congress Web Site uses a number of indexing and retrieval techniques to provide search access to its resources.
Efforts currently are under way to improve further the site's searching capabilities.
InQuery is a suite of tools enabling document indexing, query processing, query evaluation, and relevance feedback. InQuery can search across a number of LC resources and also within individual resources. Searching on the keywords Henry Ford in All Collections yields a multimedia item list including photographs, documents, and a motion picture. Each item in the list links to the bibliographic record containing a reference image that is in turn linked to a photographic enlargement. Searching on the keywords Texas judge returns a list of life history interviews containing the terms.
