639 - Web Archiving
The World Wide Web is the primary delivery mechanism for digital content. Preservation administrators need to be familiar with the tools and appropriate techniques for preservation of information delivered through the "surface" Web (static Web pages, blogs, E-mail discussion lists, etc.) and information that is part of the "deep" Web (e.g. databases, streaming media, and authenticated resources). Once Web content is captured and brought into a preservation environment, preservation administrators are responsible for transforming them into persistent formats and data structures.
