In 1998 I wrote about the future of books, and speculated about the implications of the electronic availability of books. That day is now here: the Amazon Kindle with a 2GB SD card can carry nearly 2,000 books; and an 8GB SD card is easily available. While over 120,000 books in Kindle format are available from Amazon, this does not include the additional thousands of e-books available in other formats (e.g. Mobipocket), as well as the fact that a Kindle can easily use standard HTML, Word, and PDF formats—which means you could feasibly carry every issue of Mission Frontiers, IJFM, EMQ, IBMR, Missiology, Lausanne World Pulse, whole encyclopedias, Operation World, several versions of the Bible in your favorite language, and all of the readings for the WCIU’s World Christian Foundations course. At $350, any missionary ready to buy an iPod or a cell phone should seriously consider the investment.
The Kindle is said not to be compatible with the PDF format. The Sony ereader costs $300 and is compatible.
The Kindle is in fact compatible with the PDF format. I own a Kindle and use PDFs on it. You do have to have them converted using the Kindle conversion service, and if they are very complex PDFs the conversion may not be very useful; and if they are PDFs of images, then the images would be scaled to fit the Kindle’s screen and may not be usable. But PDFs such as Mission Frontiers, or IJFM, work just fine. The same holds true for things like the World Christian Foundations readers.
