Electronic books, or eBooks, are electronic versions of written material. They can contain text, sound, images. And they exist in the form of files that can be read using a computer (Word documents, text files, web pages, PDF files, EXE files) or using an e-book reader.

To write eBooks, all you have to do is find out what you know and write as if you were talking to others. It’s not that hard and if you’ve ever written an essay for a school assignment, you already have all the prerequisites. You don’t have to be an expert on the subject of your ebook, although it helps, as most information can be found online and at your local library. You don’t even have to be a good writer, as most word processors have grammar and spell checking tools.

Today, any type of electronic book can be sold on the Internet; however, here are the most popular types with the highest levels of public demand.
