 This list initially was a clone of [stackoverflow - List of freely available programming books](http://stackoverflow.com/questions/194812/list-of-freely-available-programming-books/392926#392926) by George Stocker. Now updated, with dead links gone (hopefully) and new content.
 Moved to GitHub for collaborative updating and for the purpose of reSRC.io : [List of free programming books](http://resrc.io/list/10/list-of-free-programming-books/).
 
+The French list was based on http://progdupeu.pl/forums/sujet/43/une-banque-de-liens.
