Electronic book readers have many convenient features that people love and appreciate. For example, e-readers allow people to precisely optimize the content of each page for presentation on the screen, adjust colors, fonts, indents, and gesture control. They use electronic ink and anti-reflective filters, which allow people to read for a long time without eye strain and enjoy reading even in poor lighting conditions. Popular Calibre and Kindle Readers support text highlighting, bookmarking, and text to speech.

The variety of such hardware and software integrated directly into the Internet is wonderful. However, format compatibility problems automatically arise.
