ABSTRACT
The most common handwritten marks in the music are added barlines. Most of these appear to have been inserted by later owners of the eighteenth and nineteenth centuries, like John Stafford Smith. Such is the case in the British Library copy of the earliest printed songbook in our list, the XX Songes of 1530. The Royal College of Music copy of Ravenscroft's Pammelia, once owned by John Stafford Smith, contains eight extra catches, some of them not found elsewhere. Several pieces by Thomas Weelkes were copied into other composers' publications. Music for the metrical psalms in the The whole booke of psalmes was the staple of the English music publishing business in the late sixteenth and early seventeenth centuries and it is not surprising to find them copied into other books. The Folger Shakespeare Library contains a number of music books with additional music, some of which is in the hand of Conyers D'arcy.
