Here is what you will see when you find a downloadable ebook in NetLibrary (you must click on View Details in a search result list):
You'll need to create a free account to download books, and an additional software download (Adobe Digital Editions) may be required. The book will be accessible to for 3 days and then it will become locked, though you can access it again online through the NetLibrary database. The ebook downloads work well on a computer, and they are supposed to be transferrable to several devices, but this librarian couldn't get one to work on an iPhone. If you have luck getting one on your Nook, Sony Reader, or other compatible device (not the Kindle, though) let us know.
