The MIT Libraries—with holdings of more than 2.7 million print volumes and 2.5 million additional items, such as microforms, maps, slides, musical scores, manuscripts, recordings, and electronic resources—support all of the Institute's programs of research and study. The library system is composed of five divisional libraries, four branch libraries, and the Institute Archives and Special Collections:
Aeronautics and Astronautics Library
Barker Engineering Library
Dewey Library (management and social sciences)
Humanities Library
Lindgren Library (earth, atmospheric, and planetary sciences)
Lewis Music Library
Rotch Library of Architecture and Planning
Rotch Library Visual Collections
Science Library
A wide range of online services and resources are available through the MIT Libraries' website, at http://libraries.mit.edu/. Patrons can locate library items using the online catalog, Barton, at http://libraries.mit.edu/barton, or search over 20,000 journals, databases, and other serial publications using Vera, at http://libraries.mit.edu/vera/.
In addition, the online interlibrary loan service, at http://libraries.mit.edu/illiad/, makes available materials from other libraries throughout the world. On-site access is provided to 18 local libraries in the Boston Library Consortium.
Workshops on library resources and instructional support are offered for MIT courses and other groups, and in-depth consultation on research projects is available with subject specialists. Reference assistance is also available through the Ask Us! service, at http://libraries.mit.edu/ask/, and from library staff.
The MIT Libraries also manage DSpace (http://dspace.mit.edu/), a unique digital repository created to capture, preserve, and share MIT's intellectual output with the world. DSpace currently houses over 14,000 MIT theses.
While primarily serving the MIT community, library facilities at MIT can be used by others upon application to Document Services, Room 14-0551, for a library privilege card.
