Hey guys. This is my first post here and it looks like you all have a great resource. I read through the Fantasy/Sci-Fi recommendation thread (the 8 page one), and, along with some books that were already on my radar, made a list of books I'd like to buy/download before my Cybook Gen3 arrives. I seem to be having some trouble finding these ebooks and I don't know whether I'm doing something wrong or they just don't exist in Mobipocket format. If anyone knows where to find these or could give me a link that would be great:

-David Brin: Stardiver, Startide Rising, Uplift War
-Larry Niven: The Mote in God's Eye, Ringworld, Footfall, Lucifer's Hammer
-Asimov: The God's Themselves, Nightfall, The End of Eternity
-Orson Scott Card: Alvin Maker series (at least the first book)
-Robin Hobb: Farseer Trilogy
-David Zindell: Neverness
-Pratchett: Discworld
-Zelanzy: Chronicles of Amber

I tried to check Mobipocket, BoB, and Webscriptions, but I'm having NO luck with all of those.

Any help would be appreciated. Thanks.
