There are no known original manuscripts surviving of any of Shakespeare's plays or poems. The plays would have been commissioned and sold to the company of actors with whom Shakespeare worked. The scripts were in use by the working professional players and when they were gathered together for publication in 1623 they were in various states of completeness. After the publication of the Comedies, Histories and Tragedies in 1623 ('the First Folio') it was probably considered unnecessary to retain the original manuscript sheets. The fire that destroyed the Globe theatre in 1612[?] may have also caused the loss of the originals. The closure of the theatres during the Protectorate in 1640 would also have resulted in the dispersal of any surviving authorial papers. One manuscript of the play of Sir Thomas More survives in the British Library in which five pages are believed by scholars to have been written by Shakespeare's own hand. There are a number of other documents surviving which relate to William Shakespeare, or are signed personally by him. These are legal papers including his will.
