Cochran’s gift of 141 folios and quartos includes, among other important volumes, the first four Shakespeare Folios, one of the three known copies of the 1604 "Hamlet", and the copy of Ben Jonson’s "Works" (1616) inscribed by the author to his friend Francis Young. Over the years additional volumes of equal importance, such as first or early quartos of all the major dramatists, have been acquired by gift and purchase, and the entire collection now numbers around 300 volumes. A catalog of this collection, "The Elizabethan Club of Yale University and Its Library", prepared by Yale's Stephen Parks, was published in 1986 and considerably expanded in a 2011 edition. The club vault also holds a sample of 16th-century documents, manuscripts (for example, a letter of condolence from Queen Elizabeth to her friend Lady Southwell, 15 October 1598) and medals (one celebrating the defeat of the Spanish Armada in 1588), as well as various artifacts (a lock of Byron’s hair; a snuff box carved from a mulberry tree planted by Shakespeare at New Place, his home at Stratford; and a guest book signed by many of the club's visitors).
