Hi folks!
Chances are you know of it already, but if you go to the
Project Gutenberg you can get ebooks for free in all kinds of formats (Kindle, EPub, Mobi etc.), because the copyright license on those expired. Granted, many books are kind of... weird and might no interest anyone of you, but we have as well many treasures, like:
P. G. Wodehouse - Right Ho, Jeeves
Louisa M. Alcott - Little Women
And many fairy tales/children's books, like "Oz".
Just go and have a look; knock yourselves out! :)
