An eBook is the new type of publication. It is simply put a book that is electronic. To make a eBook all you have to do is make a book in Microsoft word or a pdf. After that you need to setup a free website or blog. Next you have to become a PayPal merchant so you can accept all types of payment methods. Finally you need to advertise that website or blog so you can get money for selling your eBook. If you prefer you could just make the eBook and then sell it on auction sites like eBay to make profit.
