Grab anything by John Keel too. I have a really great UFO book by Keel (name escapes me at the moment). Oh ... and Nick Redfern is always good. Just got his "FBI Files" book for my birthday and was highly amused to see the author as being one "Nicholas Redfern". Made me giggle anyway
.
Our Haunted Planet by any chance? I really enjoyed that. Keel is great. Fun to read, regardless of whether it's "real" or not.
I'd recommend all of Budd Hopkins' books, all of Leah Haley's work, and Karla Turner's
Taken.
I think Whitley Strieber's first few books are worth reading, especially if you want to familiarize yourself in what the rest of the UFO community is conversant with.
Kehoe and Vallée are good bets. An absolute
MUST is Marc Davenport's
Visitors from Time: Secret of the UFOs.
I also have some recommendations for the fact/fiction stuff--not really "UFO" truth, but maybe as close as you will get.
I bought and read Streiber's
The Grays and very much enjoyed it. It has stuff in it that he can't prove, but he says he has been told by reputable sources (Air Force sources, witnesses, police and other officials and military types--radar operators, pilots, etc.) about ARVs, stealth, MILABs and the like. Same thing with Majestic, except about the MJ-12 documents.
"Fictionalized" and sanitized for the protection of the innocent, just like Dragnet. And also so people still serving don't have to risk their pensions by breaking their security oaths.
I haven't read
Majestic, so I can't recommend it, but
The Grays was really good. He actually wrote about the new "invisible electro-cloth" that takes photos of what's behind it and projects it onto the front of whatever vehicle you like (in this case, a huge electrogravitic dirigible in a flat delta wing formation) before the military outed the technology just this year.
So, maybe not fictionalized, just still within the realm of secrecy. Okay, back to the NO-BS UFO booklist:
Please read the late John Mack's excellent book
Abduction: Human Encounters with Alienshttp://www.amazon.com/Abduction-Encounters-John-E-Mack/dp/0345393007--if you're not already familiar, bump it up to the top of your list.
Oh, and everything that David Jacobs ever wrote, including
The UFO Controversy in America,
UFOs and Abductions: Challenging the Borders of Knowledge, and especially
Secret Life and
The Threat.

(He'd be a good guest, too.)
