Net Books

An e-book is an electronic book. It is nothing more than an electronic file that contains the text of an existing book. One of the most confusing aspects to the e-book is the fact that they come in such a variety of formats. The purpose of an e-book is to be able to carry a library of books on something the size of the paperback book. A more complex e-book can show a film or play a music file.

Text e-books
A text e-book is the most simplistic form and all that needs to be done is write the text into a text editor or scan the text from paper using a text converter. The file format is simple and is in the standard linear form in the document. This has been used extensively for computer manuals in the past before Adobe invented their Portable Document Format (PDF). With it's simplicity it also has the advantage of being very easily searchable and portable to any platform.

Word e-books
Word documents can be made into books and are stored under the same document name. Having hyperlinks within a document allows there to be a presence of multimedia content. Multimedia files can be large especially when images are included. This means that this format is only most effective when everyone has the Microsoft Office software and where different author have to work together.

Adobe PDF e-books
The Portable Document Format books are stored in a PDF file. This type of e-book has been a massive success, as proof almost all computer and software manuals are in PDF format. This is even starting to take off well as a full e-books. However to create this it is probable that you will need specialised program such as Adobe Acrobat. With this said some operating systems can allow PDF files to be directly printed from a document.
The PDF format itself has a number of features that allows it to be useful for the presentation and layout of textual material. These features allow a PDF file to be very small compared to a similar word document. Another good prospect is that you can impliment multimedia and sucurity features such as passwords and even digital signatures. It is possible to lend e-books  for a period of time and deactivate them when this time period is up.

Reader e-books
This is designed to give the reader a feeling that they are reading a normal book. It is quite unique because it allows you to bookmark pages, make notes and also give you the option for the e-book to read to you. These formats are ususally made from a word document and have had a convertion software added to make it a single incrypted file. You can access any of your books from microsoft reader. This sort of format works well on pocket PC's and Personal Digital Assistants. It's best attribute is that it makes a good simulation of the total paperbook reading experience.

Website e-books
The most important and felxible format is created as a website in HTML or XHTML format. All the pages are linked together to create an e-book feel. It is argued that this type of e-book is the best because it allows images, animations and sound files to be added. Typically this format offers the richest multimedia experience of them all. There are simple text based websites/e-books with page to page navigation.
As a website is a collection of files it is hard to control so some website e-books have put the site into .exe format. However if this is done then it makes to process of creating an e-book longer and as a whole the resulting file could be quite large.

An e-book good or bad
There are both good and bad things about e-books here are some examples of both.
E-books are good because it allows people to carry around a vast amount of books with them on something that is the size of a small paperback. Another good thing about e-books are that most formats actually resemble a paperback book with added extras to make reading more fun and exciting.
E-books might not be liked or used by people because of the fact that however much it is made to seem like a paperback, it will never be one. Some people just like the feeling of having a real book in their hands.
