E-Book Formats

The e-book formats are of great importance, since the e-book readers do not support all formats, but only a limited number of them. As in other areas of computing, there are basically two types of formats for electronic books, free or open formats that can be used by anyone without restrictions on use, or closed proprietary formats, which have legal restrictions on use and are subject to licensing fees.
