Requests for software to read, create, or edit eBooks should use this tag.
eBooks (or, alternatively spelled E-books) are "electronic books", i.e. book-length publications in digital form. The most common format for them probably is PDF (created by Adobe), the most wide-spread open and free format EPUB, and the best known reading device Amazon's Kindle. E-books can be read on many devices like computers, tablets, and even smartphones.

When not to use this tag
You should not use it when looking for eBooks themselves. In fact, you should not even commit your question then: this site is for software recommendations, not reading tipps :)
