When the Handlist of Anglo-Saxon Manuscripts was published ten years ago it was clear that it could not claim to be perfect or complete, not only because of the well-known problems and remaining uncertainties of the subject, but also on account of the ever-increasing research work on medieval manuscripts. As a result, a first set of addenda and corrigenda to the Handlist appeared in Anglo-Saxon England 32 (2003), 293–305, and the time has now come for a second supplement intended to update and, where necessary, to correct the Handlist.

Like the first supplement, the second has profited from recent publications and, above all, from kindly provided information by friends and colleagues. Once again I owe a special debt of gratitude to Michael Gullick, who generously shared his expert knowledge with me and read a draft version of this article. What I owe to him this time is acknowledged in the individual entries; Appendices 2 and 3 could not have been written without his help and advice. I am grateful to Richard Gameson, Drew Hartzell and Rebecca Rushforth for letting me know about discoveries they made before these appeared in print. As always, Birgit Ebersperger helped to solve my bibliographical problems. All debts I have incurred, whether from personal communications or from publications, have been recorded in the respective entries. As most readers will have noted, a serious drawback of the Handlist – the lack of any references to musical notation – has been made good by Professor Hartzell's comprehensive Catalogue of Manuscripts Written or Owned in England up to 1200 Containing Music.
