Ebooks are books too!!!
Electronic books - that is books you read on computer- have same information and entail same reading experience as books in traditional form - that is books you actually hold in your hands. An ebook looks just like a Microsoft document but it is transformed into an ebook format such as PDF where reader cannot make any changes to document. There are other points of comparisons of ebooks and just regular books.
Anybody can buy an ebook traditional way, just walk into a bookstore but with ebooks you have to have a computer and internet connection and also a credit card which presupposes your finances are in good order for bank to allow you a credit card while with a traditional book no matter your financial situation even if you do not have a credit card you can purchase one as long as you have some money.
Suppose you were looking for a book on a particular subject and your local physical bookstore does not carry books on such subjects you can always find books on such subjects on net (and even subjects you have never dreamed of) and you can purchase a book from someone halfway around world and have it in minutes!
