Due to the big success of my icon-list in September I decided to look for more advantageous links for you. Here are the most interesting icon resources. You can use these sets both for commercial and private projects (as they say in their disclosures) – but to be on the safe side: check their license agreements again. Did you stumble upon a site which offers icons for commercial and private use not listed here? Feel free to publish it in your comment. After checking it will be incorporated with the next update.

If you like this list I would be happy if you share with your friends or digg this article.
