I am working on a new catalogue raisonné of Blake’s separate plates for Princeton University Press. I would appreciate hearing from anyone with information not recorded in Keynes’ Engravings by William Blake: The Separate Plates (1956), Bentley’s Blake Books (1977), or other standard reference works on the separate plates. I am interested in new information about states, printing or coloring techniques, and paper, as well as the location of unrecorded copies of the original graphics (“Joseph of Arimathea,” “The Ancient of Days,” “The Three Accusers,” etc.) and the rarer reproductive plates (“Morning Amusement,” “The Fall of Rosamund,” “Robin Hood and Clorinda,” etc.). Please write to Robert N. Essick, The Huntington Library, San Marino, Calif. 91108. I will of course acknowledge in the catalogue the source of all new information sent to me.
