Last week about 25,000 people downloaded from the site, and 5 people donated. I run this site entirely on my own - I want to be able to continue offering these books for free, but need some support to do that. If you can, please make a small donation - any amount is appreciated. Thank you! You can also support the site by buying a collection, such as the Politics, Society, Science, and Philosophy one, with 70 ebooks for only £4.00
