ebooks?

I was wondering if anyone knew a good ebook site, with preferably text files...
I guess this isn't /r/, but I don't think anyone would deliver.

Next, do you prefer to read hardcopy or on the computer?
And what book would you recommend for somebody with a reputation for not reading very many books?

hard copy and try http://www.anonib.com/bookchan/

as for the recommendation? a short book?
