Letter from L.J. [Laura Jackson] to Ellsworth Mason, 1971-07-13

"As to Walter Thigpen: You had said that you were 'thrown' by the fact that 'he would want to to continue as an active, intertwining collaborator in a bibliography. rather than turning over the information he accumulated.' If you will re-examine my letters on this subject you will find that no such 'fact' or data for a deduction of such fact was presented to you:"

....

"As to your list of what you have of mine. I have already commented on 'Barbra Rich, etc. I'd like to see you having, for your reading, what was published in Chelsea numbers 12, 14, 16, and 20/21."
