To define it simply, let's say that the electronic book (ebook) is a material of digital reading that can be visualized in a personal computer or a laptop. It is a book that has been made up to be commercialized on the internet, that is why its size, structure and design have been distinctively dealt with, so that its visualization, downloading time and possibilities of use are the appropriate ones.

Ebooks offer many advantages:

• Universal access. No matter in what part of the world you live, as long as you have access to Internet, you will always be able to buy the e-books we offer you, without any delay or post and packing charges..
  
• Immediate availability. Purchasing, unloading, saving, reading and/or printing, it's that easy.
  
• The price is lower. There is no paper, no ink, no retailers.
  
• Easy reading: The pages appear on the screen just as in a book, and with the navigator you can turn the pages one by one, or skip pages at will.
