Folger Shakespeare Library in the context of "Research library"

East Capitol Street is a major street that divides the northeast and southeast quadrants of Washington, D.C., United States. It runs due east from the United States Capitol to the DC-Maryland border. The street is uninterrupted until Lincoln Park then continues eastward around the RFK Stadium campus. East of the stadium, East Capitol crosses the Anacostia River via the Whitney Young Memorial Bridge and then goes underneath Route 295 before crossing into Prince George's County, Maryland, where it becomes Maryland State Highway 214.

The western stretch of East Capitol Street passes through the Capitol Hill and Hill East neighborhoods. East Capitol Street is home to the Folger Shakespeare Library, US-Asia Institute, Les Aspin Center for Government, East Capitol Street Car Barn, D.C. Armory, and the future New Commanders Stadium.

Quarto (abbreviated Qto, 4to or 4º) is the format of a book or pamphlet produced from full sheets printed with eight pages of text, four to a side, then folded twice to produce four leaves. The leaves are then trimmed along the folds to produce eight book pages. Each printed page presents as one-fourth size of the full sheet.

The earliest known European printed book is a quarto, the Sibyllenbuch, believed to have been printed by Johannes Gutenberg in 1452–53, before the Gutenberg Bible, surviving only as a fragment. Quarto is also used as a general description of size of books that are about 12 inches (30 cm) tall, and as such does not necessarily indicate the actual printing format of the books, which may even be unknown, as is the case for many modern books. These terms are discussed in greater detail in book sizes.

Henry Clay Folger Jr. (June 18, 1857 – June 11, 1930) was an American businessman who was president and later chairman of Standard Oil of New York, a collector of Shakespeareana, and founder of the Folger Shakespeare Library.

Emily Jordan Folger (May 15, 1858 – February 21, 1936) was the co-founder of the Folger Shakespeare Library alongside her husband Henry Clay Folger. During her husband's lifetime, she assisted him in building the world's largest collection of Shakespeare materials. After his death in 1930, she funded the completion of the Folger Shakespeare Library to house the collection, remaining involved with its administration until her death in 1936.

In 1932, she became the third woman to receive an honorary degree from Amherst College, following Mary Emma Woolley, president of Mount Holyoke College, in 1901; and Martha Dickinson Bianchi, editor of Emily Dickinson's poems, in 1931.

Shakespeare Quarterly is a peer-reviewed academic journal established in 1950 by the Shakespeare Association of America. It is now under the auspices of the Folger Shakespeare Library. Along with book and performance criticism, Shakespeare Quarterly incorporates scholarly research and essays on Shakespeare and the age in which he worked, particularly those that explore new perspectives. It includes a special section devoted to the latest ideas in Shakespeare scholarship.

As a companion, the Folger Library also publishes the reference database World Shakespeare Bibliography Online, which contains more than 125,000 annotated bibliographical references and several hundred thousand reviews.

The National Union Catalog (NUC) is a printed catalog of books catalogued by the Library of Congress and other American and Canadian libraries, issued beginning in the 1950s. The National Union Catalog is divided into two series: the Pre-1956 Imprints is a 754-volume set containing all older records in a consolidated alphabetical format, while post-1955 volumes continue to be published serially. Since 1983, the NUC has been issued on microfiche. It is not related to the National Union Catalog of Manuscript Collections (NUCMC).
