What is an eBook?

Electronic or digital book (e-book) is a book-publication in digital form, readable on computers or other electronic devices (tablet, mobile phones, computers). Although sometimes an e-book is defined as an electronic version of a printed book, many e-books exist without any printed equivalent, and include multimedia (audio, video, images, animation) and interactive objects with which a reader can interact facilitating the learning process.

There are numerous formats and types of e-books, with varying degrees of support by electronic readers and mobile devices. The most popular formats are EPUB and MOBI. The EPUB standard is based on the same technologies used by the World Wide Web, which makes it more popular with a large number of devices and e-readers.

E-Book Advantages


Video, sound, three-dimensional images, simulations, interactive exercises, online notetaking, animation, online dictionaries, etc. are some of the new features e-books have that enlivens the access to knowledge.


On the first day of the semester, without any delay, all the course materials are available to the student. Students have access to different materials per subject area, not just one, as the case is today.


Printed books have physical space limitations, unlike e-books, where someone can have as many e-books as it is allowed by the storage space of the device.


Reading in poor lighting conditions, changing font size or background color, adding notes, reading for visually impaired users are some possibilities offered by the use of an e-book, depending on the e-reader.


Access from everywhere! You can access an e-book from school, the library, the auditorium and from home.


As mobile devices increase their storage space, anyone can transport an entire library wherever they go. It is also possible to create backups, so as to avoid data loss.
