The Main Reading Room (MRR) houses a large general reference collection
emphasizing humanities, social sciences, and bibliography. The mission
of the Main Reading Room Reference Collection is to provide comprehensive
reference and research materials in the humanities, especially religion,
philosophy, language, literature, art, and history, as well as in
biography, bibliography, and library science. The collection also
covers the social sciences, especially anthropology, criminology, education, political science, psychology, sociology, and women's studies. (for business and economics see Business
Reference Services), especially psychology, sociology, political
science, and education. Only a few titles are held in subjects where
a specialized reading room exists such as business, music,
law, and science and technology.
The MRR collection contains over 16,000 titles in about 56,000 volumes. The books are on open shelves in the alcoves (MRR Alc) of the Main Reading Room on both the main floor and the first balcony; on Decks 7, 46, and 16 adjacent to the reading room; and in the Reference Assistance Room (MRR Ref Desk) as you enter the reading room. Subject classes A-P are shelved in the reading room; classes Q-Z are shelved on Deck 7.
The titles assigned to the MRR reference collection are designated Reference – Main Reading Room in the online public access catalog. All reference copies appear last--at the bottom of the list of copies in the OPAC. To find out what is available on the open shelves of the Main Reading Room for a particular subject or classification number, do a keyword search including MRR (e.g., MRR adult education, MRR Biog Australia, MRR JK1012, MRR Ref Desk Z733.U6). Reference books are instantly available; they do not have to be ordered from the stacks.

This ready-reference collection of approximately 800 titles is located in the Reference Assistance Room (RAR) at the entrance to the reading room (LJ 100). Here reference librarians are on duty during the hours the Main Reading Room is open. The Reference Desk titles are the volumes most frequently consulted by researchers and librarians. The titles include almanacs, dictionaries, encyclopedias, indexes, statistical sources, directories, guides to colleges and scholarships, thesauri, poetry indexes, guides to government publications, and directories of periodicals.
The reference desk collection for Local History and Genealogy Reference Services is also located in the Reference Assistance Room on the right side as you enter the room.
The microform guides which have Library of Congress call numbers are also located in the RAR on the right.

Current U.S. telephone, city, and criss-cross directories and some current foreign telephone directories are located on Deck 46 adjacent to the Main Reading Room.
Earlier editions of these directories do not have call numbers but can be requested using a paper call slip. Include the city and state for U.S. directories plus the type of directory being requested (e.g., city directory, telephone directory, criss-cross directory) and the dates wanted. Some information on which directories the Library has can be found by consulting the directory listings on the Local History and Genealogy Reference Services Bibliography and Guides web page.
Foreign city directories are cataloged and have call numbers. A few foreign city directories with call numbers are shelved with the uncataloged foreign directories on Deck 46. Telephone directories in non-Roman alphabets should be requested in the appropriate area studies reading room.

The over 400 published and unpublished guides to the collections
of the Microform
Reading Room are housed in the Reference Assistance Room of
the Main Reading Room and in the Microform and Electronic Resources Center. These guides often represent the only listing
of items in the vast microform collections. These collections include
reproductions as well as original micropublications and contain
books, serials, manuscripts, pamphlets, photographs, dissertations,
government documents, broadcasting transcripts, and a variety of
ephemera. The languages covered include the same languages found
in the Library's general hardcopy collection as well as several
non-Roman script languages; the range of subjects is as broad, if
not broader, than those found in the book collections. Listings
of the collections and the guides can be found in A
Guide to the Microform Collections in the Humanities and Social
Sciences Division of the Library of Congress. Information about
microform collections and guides can also be found in the Library's
online catalog by choosing
the "Command Keyword" option and using the search term "microform"
in combination with other search terms (e.g. "slave narratives"
AND microform). Please consult a reference librarian for assistance.
There are also online guides to microform collections
on the following subjects:

Over 240 volumes of quotations are shelved in call number order in the Reference Assistance Room in the Main Reading Room. These include works on specific subjects (such as politics, women, religion), as well as general collections of quotations. Titles devoted entirely to quotations by a single author are not shelved here but are shelved by call number in the MRR alcoves, as are a few concordances to the works of individuals. The Library's general collections in the closed stacks contain numerous additional dictionaries of quotations and concordances. These can be identified using the computer and card catalogs; consult a reference librarian for further assistance. In addition there are many online quotation databases.
