Folger Shakespeare Library

The Plimpton "Sieve Portrait of Queen Elizabeth I" is an oil painting by English painter George Gower dated 1579, and now in the collection of the Folger Shakespeare Library in Washington, D.C. It is one of three near-identical portraits of Elizabeth I by Gower that represent the queen holding a symbolic sieve.
 It was acquired by George Arthur Plimpton in 1930, hence the name.
 His son, Francis T. P. Plimpton, willed it to the Folger.
The Dering Manuscript is the earliest extant manuscript text of any play by William Shakespeare.
 The manuscript combines "Part 1" and "Part 2" of "Henry IV" into a single-play redaction.
 Scholarly consensus indicates that the manuscript was revised in the early 17th century by Sir Edward Dering, a man known for his interest in literature and theater.
 Dering prepared his redaction for an amateur performance starring friends and family at Surrenden Manor, Kent, where the manuscript was discovered in 1844.
 This is the earliest known instance of an amateur production of Shakespeare in England.
 Sourced from the 1613 fifth quarto of "Part 1" and the 1600 first quarto of "Part 2", the Dering Manuscript contains many textual differences from published quarto and folio editions of the plays.
 Dering cut nearly 3000 lines of Shakespearian text (including significant abridgment of the character of Falstaff) and added some 50 lines of his own invention along with numerous minor interventions.
 The Dering Manuscript is currently a part of the collection at the Folger Shakespeare Library in Washington, DC (Folger MS V.b.34).

Samuel Gilburne (fl.
 1605, d. after 1623) was an Elizabethan actor who is listed as one of the "Principall Actors" in the prefatory material of the First Folio of William Shakespeare's plays.
 Gilburne is named as a former apprentice to Augustine Phillips, another member of Shakespeare's company, in Phillips' will dated 4 May 1605, in which Gilburne is bequeathed 40 shillings, Phillips's "mouse-colored" velvet hose, his black taffeta suit and white taffeta doublet, his purple cloak, his sword and dagger, and his bass viol.
 A copy of the First Folio held at the Folger Shakespeare Library has a signature thought to be Gilburne's.
False Folio is the term that Shakespeare scholars and bibliographers have applied to William Jaggard's printing of ten Shakespearean and pseudo-Shakespearean plays together in 1619, the first attempt to collect Shakespeare's work in a single volume.
 The only complete extant copy is part of the collection of the Folger Shakespeare Library in Washington, DC.

The Rosenbach is located within two 19th-century townhouses at 2008 and 2010 Delancey Place in Philadelphia.
 The historic houses contain the collections and treasures of Philip Rosenbach and his younger brother Dr. A. S. W. Rosenbach.
 The brothers owned the Rosenbach Company which became the preeminent dealer of rare books, manuscripts and decorative arts during the first half of the 20th century.
 Dr. Rosenbach in particular was seminal in the rare book world, helping to build libraries such as the Widener Library at Harvard, The Huntington Library and the Folger Shakespeare Library.
 In 2013, the Rosenbach became a subsidiary of the Free Library of Philadelphia Foundation, but maintains its own board and operates independently of the public library system.
