I also don't have all my books on-hand, but I can try to summarize...
I have everything by Linda Godfrey (I've met her in person and she's awesome).
Mysterious America (Coleman, met him too and he's also very down-to-earth and awesome)
Passing Strange and
Green Mountain Ghosts, Ghouls, & Unsolved Mysteries (Citro, excellent writer)
Invisible Residents,
Things & More Things (reprint), and
Uninvited Visitors (Sanderson et al.)
Everything by Dennis Boyer (
Northern Frights is the only one that comes to mind ATM)
A Geo-Bibliography of Anomalies by George Eberhart (It was going for $250 at one point but I got it for $60)
Ghosts of the Air and
Natural or Supernatural by Martin Caidin (Amazing books!)
Into the Bermuda Triangle: Pursuing the Truth Behind the World's Greatest Mystery by Quasar
Invisible Horizons (Gaddis, as Gerhard1 pointed out)
Strange World by Frank Edwards (My go-to from when I was a little kid and just getting into this stuff)
Encyclopedia of the Strange by Cohen
The Vengeful Djinn by Rosemary Ellen Guiley
Invizikids: The Curious Enigma of Imaginary Childhood Friends by Hallowell
The Inhumanoids by Nunnelly and Redfern (really good stuff in about half the book)
Three Men Seeking Monsters and
Memoirs of a Monster Hunter by Redfern (I've read good and bad books by him and these two are very enjoyable and well-written.)
Hunt for the Skinwalker by Kelleher and Knapp
And there are a bunch more which I'm too lazy to type up at the moment. These are ones that really stick with me though.
I've included all those links because there are similar titles by different authors and some just plain don't come up with a standard search on Amazon.
I'll be moving in a few months and I think it would be cool to just post hi-res pictures of our "Fortean" bookshelves...when I get re-situated again.
