After having Tumblebooks as part of our school's online library resources, I was excited about exploring more eBook and Audio eBook options. Unfortunately, World EBook Fair requires a fee to access and search their database. Granted the annual fee is only $8.95, but I couldn't find a way to sample one of the books to see if it was worth subscribing to. I was able to search the Gutenberg Project's database, but had difficulty finding a link to browse their subjects. I tried an advanced search using the term "children" for subject, "English" for language and "Audio book, Human-read" for category and got 26 results. I decided to listen to an audio reading of the Velveteen Rabbit and learned that the recording came from LibriVox. The voice was not to my liking, but realize that narrations are done by volunteers and won't always insure consistent high quality. When I broadened my search to "any" for category, I found 329 books, which had many fairytales and folktales listed.
When also searched the Best Places to Get Free Books link, some of the listings were a bit misleading. Audible.com is not a free service; instead it only gives you a 14-day free trial.
