Actually there are 973 eBooks available to Berkeley Heights residents at ListenNJ.com, but by the end of the month we'll have passed the one thousand mark. We're not talking free ebooks of dusty out-of-copyright classics, but free ebooks like The Girl with the Dragon Tattoo.
The eBooks are in the Adobe ePub format, which work with the Barnes and Noble Nook, the Sony Reader and the Kobo, the Borders e-reader. Now that Apple and Adobe are taking steps to play better together, the iPhone will eventually be a supported reader (we don't know when).
The easiest way to see what titles are immediately available is to go to Advanced Search and select eBook as the format, check the "Only show titles with copies available" box and click Search. That'll show you about 300 currently available titles. You can also put yourself on the waiting list for up to 5 eBooks.
The eBook will magically disappear from your device on the due date (7, 10 or 14 days after you check it out; your choice). Even if it's turned off (we've tried). Or you can return it early if you hate it (useful because there is a 5-book checkout limit). There is a Quick Start guide available on the ListenNJ site that will help you download Adobe Digital Editions, which is the program that syncs the ebook from your computer to your e-reader.
