I’ve just posted the second part of the accession list for Boyd’s personal papers. You can find it under “John R. Boyd” on the Articles page (tab above).
I don’t have the first part. If any one does and would be so kind as to send me a PDF, I’d be happy to post it, too. In the meantime, the first part consists primarily of works on history and military topics. Many of these, and virtually all of the ones he actually used, are included in the Sources section at the end of Patterns of Conflict.
