Easy to use icon sets are always nice and useful to have ready to hand. Most of the designers call the attention to their users’ interest by using icons. They can be applied basically in every project you are going to be working on. Using them reasonably, icons can direct users’ interest to the key-segments of an article or specific site sections, communicating the message of the site in a more successful way.

Many of these sets can be used for free only for private projects, however most of them can also be used in commercial projects. In both cases - before using icon sets please read the license agreement carefully; it can change from time to time.
