Do you know what an eBooks reader is? In the past, we have all sort of printing reading materials like magazines and books. Later, publishers coming out with soft copy of the printed reading materials, and the soft copy were published in a website where subscribers can download the soft copy version of the magazines or books. However, because of easy accessibility to this soft copy, subscribers can just download a softcopy and then share the reading materials among friends.
