For the study of English literature of the later sixteenth and the seventeenth centuries—for the Elizabethan era, the Jacobean era, the Caroline era, and especially for English Renaissance theatre—the Stationers' Register is a crucial and essential resource: it provides factual information and hard data that is available nowhere else. Together with the records of the Master of the Revels (which relate to dramatic performance rather than publication), the Stationers' Register supplies many of the certain facts scholars possess on the works of William Shakespeare, Ben Jonson, and all of their immediate predecessors, contemporaries, and successors.
By paying a fee of 4 to 6 pence, a bookseller could register his right to publish a given work. One example: the Stationers' Register reveals that on November 26, 1607, the stationers John Busby and Nathaniel Butter claimed the right to print "A booke called Master William Shakespeare his historye of Kinge Lear, as yt was played before the Kinges maiestie at Whitehall vppon Sainct Stephens night at Christmas Last, by his maiesties servantes playinge vsually at the Globe on the Banksyde." (They paid sixpence.)
Enforcement of regulations in this historical era was never as thorough as in the modern world; books were sometimes published without registration, and other irregulairites also occurred. In some cases, the companies of actors appear to have registered plays through co-operative stationers, with the express purpose of forestalling the publication of a play when publication was not in their interest.
In 1710, the Copyright Act or Statute of Anne entered into force, superseding company provisions pertaining to the Register. The company continued to offer some form of registration of works until February 2000.
