General/miscellaneous Topics & Subjects PR2989 - 3112 (best to use the LC Classification 2008 to break these down)
Subject headings for William Shakespeare can be found in the 30th edition (2007) of the Library of Congress Subject Headings, the five-volume set of large red books located on the green cabinet beneath Shakespeare's portrait on the library's seventh floor. Use the heading Shakespeare, William, 1564 - 1616 (volume V pages 6732 - 6738). For a shelf-browsing, call number approach, use the 2008 edition of the Library of Congress Classification for PR, PS, and PZ, located adjacent to the Library of Congress Subject Headings on the green cabinet. The classification for the entire class P of language and literature can be found here:

Books that are entirely, cover-to-cover, by or about William Shakespeare may be located by performing either an author or subject search in the library's catalog, using as search terms the author's name (in last-name first order). For the broader subject of renaissance drama, some additional useful subject headings are:
History of English Literature -- Drama
16th century PR646 - 670
17th century PR671 - 700
