Larry, thanks for your response. I confess to still being a little unclear about how the material that is known as the Ferrell archive or collection actually became part of that archive or collection. My impression, based on what I've read previously about Ferrell, is that the process of accumulating documents apparently took decades, but the exact means by which the documents (and other materials) made their way from various places, such as, perhaps, NARA, to Ferrell's home in Dallas, remains somewhat opaque to me. (I understand, based on a story in The Dallas Morning News, that some, if not most, of the Ferrell material is now at Baylor University in Waco, Texas.)
