You find introductions to the languages as well as topics that are best suitable for advanced users. If you are currently learning a programming language or always had the desire to learn one but never wanted to pay lots of money for books this site is for you.

Update: You can still access the website here. Programming books are listed in categories that are all listed on the side’s sidebar. A click on a sidebar entry such as .Net displays all the books that are included in the category. Books are listed by name, author, format and price. Especially the author and format are important. The format for instance tells you how and where you can read the book.

Some are available as online video screencasts, other as online viewable HTML files, and others as downloads. Requirements are listed on the same page, some may for instance require a specific software development suite installed on the computer.

All programming books listed on the site are free, from what I can tell. At least they are listed as that. Since they are pointing to regular company web pages and not file hosters, it is almost certain that it is legal to download them to your computer or to access them online.

A search is provided at the top which lets you find specific books or issues faster. The site furthermore lists the top ten books based on overall popularity at the top of each page. You find C++, J2EE, C# or Rad Studio books listed there.
