Based in Oxford, Peter Kidd has since 2006 been a freelance researcher, working primarily on medieval manuscripts, with a particular specialisation in cataloguing and provenance research of liturgical and illuminated books, leaves, and cuttings.
He also works on post-medieval manuscripts, archives, and inventories, and on the provenance of printed books, and has copy-edited and proof-read books by other authors for the Bodleian Library and for Brepols.
He has written hardcopy catalogues for The McCarthy Collection, The Queen's College, Oxford , the Bodleian Library , the Huntington Library , Sam Fogg , and auction houses, and an online catalogue for the College of Physicians, Philadelphia . He collaborated on a study of the St Albans Psalter to accompany an exhibition at the Getty Museum, drawing on his work for a previous facsimile commentary.
