Online Reference Sources for Cataloging Visual Materials

Prints and Photographs Division, Library of Congress, Washington, D.C., 20540-4730

Librarians and archivists who describe photographs, cartoons, posters, drawings, prints, and other visual materials rely on a wide variety of Web-based reference sources to gather or confirm cataloging data. This selected list covers sources that can help you discover information about the creators, subjects, and geographical locations that commonly occur with still pictures. The list also cites tools for recognizing and translating foreign languages; for converting measurements and dates; for identifying formats and types of visual materials; and for dating images.

The selected resources represent free Web sites used by Library of Congress staff to catalog material in a general documentary picture collection. Many of the sites feature visual images for easy comparison to what you are cataloging. Suggestions for additional resources are welcome. Subscription-based internet resources are also valuable and should be consulted when available. Most subscription databases at the Library of Congress are available only for on-site access.

For a list of standards and tools used to create catalog records, see the "Visual Materials: Cataloging and Processing Bibliography." For additional sources relating to visual media, see: Popular Photographic Print Processes Represented in the Prints and Photographs Division and Printmaking Processes: a Webliography. For resources useful for researching pictures, see: Researcher's Toolbox .

Disclaimer icon The Library of Congress does not maintain most of these sites. Users should direct concerns about these links to their respective site administrators or webmasters.
