"The Memories: JFK: 1961-1963" by Cecil Stoughton, Chester V. Clifton, and Hugh Sidey (1973) -- This book isn't really a book about the assassination, but I put it on my "favorites" list anyway.
"The Killing Of A President" by Robert J. Groden (1993) -- This book is recommended only for the great pictures it contains. I certainly wouldn't recommend it for anything else, particularly the outlandish theories presented in the book, which include Mr. Groden's shot-by-shot shooting scenario, where Groden says it's very likely that ZERO shots (out of up to TEN!) came from the "Oswald" window on the sixth floor of the TSBD, even though Groden thinks Oswald was being framed and set up as the proverbial "patsy" from the sixth-floor window that Groden thinks it's likely nobody was firing from. (See Pages 20 through 40 of TKOAP for additional robust laughs.)
