I would worry about the collection a bit as one of the reviews mentioned that all of each writer's output is in a single file. Thus all of Dickens is in one 10 MB file.
I have gotten good results from the Silk Pagoda (BlackMask) CD for the Sony Reader. It is in PDF formatted for the Sony/Gen3/Kindle screen.

I'm with Zelda on this one, the best formatted works are here at MobileRead.
