Encoded Archival Description is the emerging standard for archival finding aids and is used by Library of Congress and other research institutions. Finding aids are inventories, registers, indexes, or guides that provide detailed information about specific collections. Standardizing the format of these tools makes it easier to display them on a network.

Encoded Archival Description DTD (Document Type Definition) that assists in the creation of electronic finding aids. Developed at UC Berkeley, it is now maintained as a standard by the Library of Congress and sponsored by the Society of American Archivists. An EAD can be used to represent complete archival structures, including hierarchies and associations. See the Library of Congress EAD glossary for more terms.

Encoded Archival Description (Society of American Archivists, maintained by the Library of Congress): A data interchange standard that defines the structural elements (and their interrelationships) to be used in creating archival inventories or registers (finding aids that supplement broad collection descriptions for archival collections).

Encoded Archival Description, an SGML DTD that represents a highly structured way to create digital finding aids for a grouping of archival or manuscript materials.

Encoded Archival Description. The EAD is an SGML (Standard Generalized Markup Language) DTD (Document Type Definition) intended to assist in the creation of electronic finding aids. Developed at UC-Berkeley, it is now maintained and supported as a standard by the Library of Congress and sponsored by the Society of American Archivists. The EAD can be used to represent complete archival structures, including hierarchies and associations. The kinds of functionality that EAD affords can also be implemented using Dublin Core, and it is also possible to migrate records from Dublin Core into the EAD format if necessary. More information on EAD is available at http://www.loc.gov/ead EDMS is an acronym for Electronic Document Management System. Effective ISO Analogous to film speed. A higher number means the camera sensor needs less light to make a good exposure. Higher numbers can help in situations of low light where flash may not be effective, e.g., large interiors in low light.

A standard for encoding archival finding aids using the Standard Generalized Markup Language (SGML).

Encoded Archival Description. A standard for encoding archival finding aids using Extensible Markup Language (XML).

A DTD used to encode electronic versions of finding aids for archival materials.

Employment Authorization Document. Granted by the USCIS to temporary visa holders for permission to work in the United States. There can be many different situations for a work authorization such as adjustment of status applicants, F1 students that want practical training, and spouses of L1 visa holders. More Information

equivalent air depth. When diving on Nitrox, less nitrogen is absorbed at a given depth than when using air. For example, the same amount of nitrogen would be absorbed on a Nitrox dive to 63 fsw (feet of sea water/19 m) as an air dive to 50 fsw (15 m) with the same bottom time.
