Packt Publishing, one of the publishing houses, which kindly provides me books for reviews and personal needs, has decided to present anyone with a different free e-book every day. This means, that if you go to this link, every day, you would be surprised with a new IT book. With its source code, which Packt Publishing always provides on its website. The formats of the books are – Kindle, PDF and a browser format – pretty much all you need!
Why do they do it? I think because it is a good for advertisement reasons and thus you get acquainted with their website and the quality of their books. So, anyhow – just take a free book, they have plenty! 🙂
