Amazing materials you can get for free! Check out this repository of free programming books.
Swiss developer Victor Felder has taken a list created with the help of the community of web design and development forum Stack Overflow, updated the content with new and corrected links and shared it over on GitHub. The list is indexed in several ways, covers over 80 programming languages and it has over 500 books.
For example, I found 14 book recommendations to improve my programming skills. Thank you, Victor!
