Just got a tablet and was looking for a good site to download some books to see if I like reading from a tablet.
Also, as I don’t have wifi, can I just download them to my computer and transfer them to the tablet that way?
Tablets are new to me, so I’m a bit clueless.

Plenty on the usual download sites but google Gutenberg project

here

You haven’t said what flavour it is, but platform agnostic readers like Kindle, Bluefire, eBookMobi and ereader will allow you to search for books via Gutenberg and other sources, and if you register with these people:
http://www.ereaderiq.co.uk/
then they’ll send you daily updates with free books you can download.
Reading on a pad is no different to reading a paperback, you set the page brightness, text size to suit your eyesight, and that’s about it. Easier to read in the dark, mind!
I’ve managed to find lots of ePub copies of old SF books, like Roger Zelazny’s Amber series, which open in eBookMobi, and some, which were paid for, which would only open in Bluefire, because of the Adobe DRM.
There’s loads out there, once you know what to look for, and there’s tutorials available. Most will open straight into the ereader app, others can be dragged from iTunes, there’s lots of different options.
Enjoy, I must have getting on for 200+ books on my iPad, many free, many paid for, I’m sure you’ll find it impossible to put down once you get some good books on it. 😀

Cheers guys, very helpful.
I have just downloaded loads of books I would never have found in shops.
Off to try and get through them 🙂

Google has 100s of thousands of books free to download ie out of copyright. You could also try Ebay for the same thing but on a CD all free and legal to download. Not nescearily ancient books.

And other sites I think this is one http://archive.org/details/inoldwest00ruxtgoog
