Missing books

So in the process of adding ISBN numbers to the books in my database, I also was able to take an inventory and find out what books have gone missing.

I think I know where these are:
Chicks in Chainmail - Friesner, Esther ed.
Slaves of the Volcano God - Gardner, Craig Shaw
Bride of the Slime Monster - Gardner, Craig Shaw
Revenge of the Fluffy Bunnies - Gardner, Craig Shaw
Knights of Madness - Haining, Peter ed.
Complete Pegana, The - Dunsany, Lord

I don't remember where these are:
Midsummer Tempest, A - Anderson, Poul
Ethan of Athos - Bujold, Lois McMaster
Who's Afraid of Beowulf? - Holt, Tom
Three Men in a Boat - Jerome, Jerome K.
Renegades of Time - Jones, Raymond F.
Knights Next Door, The - O'Donnell, Patrick
Nineteen Eighty-four - Orwell, George
Berserker Throne - Saberhagen, Fred
Cuckoo's Egg, The - Stoll, Cliff
Fire Watch - Willis, Connie

If anyone has one of the above from me, could you let me know?
