How much data is represented by the Librarys physical and digital collections?
Matt Raymond, Director of Communications at the Library of Congress, provides an overview of how much data the Library’s physical and digital content represents on the Library of Congress blog. Mr. Raymond notes that, as of February 11, 2009, “the approximate amount of [the Library’s] collections that are digitized and freely and publicly available on the Internet is about 74 terabytes.

A single item can consist of multiple files, and the ratio between the numbers of catalog records, physical objects, and digital files that represent a single item can vary considerably, depending largely on the type of physical objects and how they have been cataloged, scanned, and presented on the Library’s Web site.
In an April 15, 2010, press release, the Library’s Public Affairs Office notes that “the Library holds more than 167 terabytes of web-based information, including legal blogs, websites of candidates for national office and websites of Members of Congress.” In addition, Matt Raymond, Director of Communications at the Library of Congress, provides an overview of how much data the Library’s physical and digital content represents on the Library of Congress blog.
