E Books

I hope this is the right Forum for this thread...
I have a PDA which I use for lots of different things, I have read a lot of E Books on it as well (These all came from 1 Disc on E Bay) as I work away on a regular basis I want to track down some others to download onto my PDA but can't find any really good sites. Have you any suggestions as to where I might try to get some up to date titles to read.
Many Thanks
