This curated compendium of glossaries includes a profusion of valuable resources related to eDiscovery, big data, information governance, digital forensics, privacy, and security:
The Sedona Conference
The Sedona Conference Glossary is published as a tool to assist in the understanding and discussion of electronic discovery and electronic information management issues. For this excellent seminal work I'd like to personally thank—in addition to the various authors—Richard Braman (in memoriam), founder and Executive Director of The Second Conference, for his numerous contributions to our profession.

eDiscovery People's Glossary: File Types of Electronically Stored Information (ESI) provides details about particular file types and extensions in all known ESI format categories. The objective of this glossary is to provide in one place all file types with known extensions for every category of ESI. To keep pace with inventions of new information types and formats, the eDiscovery People continuously update this glossary.

U.S. National Archives & Records Administration
The U.S. National Archives & Records Administration has published archival terminology that includes a flexible group of common words that have acquired specialized meanings for archivists. Frequently used archival terms are those that describe documentary materials and archival institutions. Visit the site to view an early release, free version.
Possibly the most significant impact on archival language and professional boundaries resulted from the challenges of electronic records. E-records forced archivists into collaborations with different disciplines. In response, archivists adopted terms from information technology, publishing, and knowledge management. They began to grapple with born-digital documents and to become familiar with arcane aspects of technology used to record and authenticate electronic documents, such as ciphers, encryption keys, and encoding schemes. At the same time, other professions adopted—sometimes appropriated—archival terms. The very word that identifies the profession, archives, took on the meaning of offline storage and backup.
