Clarence Jones currently has seven books available in both print and e-book versions:
All can be accessed, with complete Tables of Contents and the ability to read an internal section (free) from the Home Page of this website.
e-books now offer a huge range of options. And you don't need a dedicated e-book reader to collect and/or read them.
The amazon.com reader is called Kindle. For now, it seems to be the most popular. The Barnes and Noble device is a Nook. There's also a Sony Reader, another by Google, and others. Unfortunately, they use different formats. But as this technology matures, that will become easier. And there are free readers that can be downloaded to your computer or smart phone for reading just about any e-book available.
All of the books above are available in both paperback and e-book versions at amazon.com. But the e-book versions there can only be read by a Kindle.
All other formats are available at www.smashwords.com. Smashwords is a distributor that wholesales e-books to online booksellers.
The most universal text format is PDF (Adobe Acrobat), which has become the worldwide standard. Even online government documents and IRS forms are created in this format, and virtually all computers have the free Adobe Acrobat Reader.
After Kindle, the most popular e-book format is E-PUB. Nooks use this format. Our choice for reading e-books on a computer screen is Adobe's free, downloadable Digital Editions, with the book in E-PUB format. You can get Jones' books in this (and all other formats) at Smashwords.
If you're new to e-books, you should also be aware of their quirks. There are no page numbers, for instance, because readers can adjust the size of the onscreen type, and that changes the number of pages. And because there are no page numbers, the usual index and table of contents won't work, either, unless they show a link to another spot in the book instead of a page number. Conversion to the various e-book formats can also create some strange things. Bullet lists, for instance, often put a question mark where the bullet ought to be. Font choice and size is extremely limited. But this technology is in its infancy. With time, the polish we're accustomed to in printed matter will also come to this new medium.
NOTE by Clarence Jones: I'm one of the few old geezers who prefers to read e-books rather than printed ones. Largely because I can adjust the type to my aging eyes. And they're easier/more compact to take with you. As younger generations who grew up with electronic screens mature, they will probably prefer e-books, too. I predict that the printed book will someday be a rare commodity. e-books are easier to produce, a lot cheaper, and can be instantly updated. You can't do that with a printed book.
