With modern technology, the Ebook has become probably one of the most popular methods of marketing and publishing books. Self publishing has never been easier. On the other hand, finding and buying a book has never been a difficult task. The Ebook comes in different guises and is designed to be read in different ways. With the advent of the 'Tablet' and 'Kindle' as we all know them, locating and reading an Ebook is now incredibly simple... and quite inexpensive too. Some other types of Ebook are simply the subject wrapped up in a PDF file which can be simply read on a tablet or a laptop. Ebooks, especially Self Help ones are available from so many different sources, it becomes quite a headache comparing and choosing. I have been operating a couple of Self Help Ebook web sites over the years, which sell a wide range of inexpensive books and are obtained by a simple download after the purchase stage. I write some of them myself and others I have been recommended or researched.
