One of the neat features of the Sony Reader is that you can “borrow” electronic books from participating libraries, including ones in New York, Chicago and my public library in Seattle. So I went to digital media page on its Web site and searched for Eclipse. It turns out that six of the library’s eight copies of the book in Adobe’s eBook format, which works with Sony’s eBook devices, were available to borrow for 21 days. I typed in my library card number and PIN, clicked download, and a few seconds later, the book was on my PC. Then, I connected the Sony Reader via the USB port and the book zipped over to my device.
