How to Choose A Suitable eBook Format?
With the popularity of eBook devices such as iPad, iPhone, iTouch, Sony Reader, and Kindle, more and more prefer to read an eBook rather than a real paper book. Then choosing a suitable eBook format is essential. Currently there are many different eBook formats from which to choose.
These are the most common current eBook formats:
EPUB — .epub
Microsoft Reader — .lit
Kindle — .azw
Mobipocket — .prc
eReader (Palm) — .pdb
There are other formats that can usually be read by e-reader devices, such as .txt and Word files, but I don't really consider those to be actual eBooks. Though most e-readers can display those types of files, they're really just general text files that you use on your computer. The most suitable eBook format to you should base on what kind of computer or e-reading device you use. Here is list to get you started:
PDF — Windows, Mac, Nook, Sony Reader, Kobo, Cool-er, Cybook, BeBook, Pandigital Novel, iOS (Apple devices with Bluefire Reader)
EPUB — Windows, Mac, Nook, Sony Reader, Kobo, Cool-er, Cybook, BeBook, Pandigital Novel, iOS (Apple devices with Bluefire Reader)
Microsoft Reader — Windows, Windows Mobile
Mobipocket — Windows, Windows Mobile, Palm OS, Blackberry, iRex iLiad, Nokia
eReader (Palm) — Windows, Mac, Palm OS, Windows Mobile, iOS (Apple devices with Stanza)
Kindle — Amazon Kindle
