This is an interesting article I came across online. Will Kindles Kill Libraries? That's the 64-million-$$$ question. While quite a few people own eReaders and like them, many, many more swear they will stick with real books. Guess we'll have to wait and see. I will say though, that Overdrive, the major distributor of eBooks to libraries has a way to go.
I've researched Overdrive a little, thinking it might be time for my library to get on board. However, every time I check on the availability of a book I might want to read there is always a waiting list. Sometimes two on the list, sometimes 5 or more. I think the record was 26. Multiply that figure by the 2 or 3 week checkout period and you can see how long it will be before #27 gets the book. Waaaaaaaayyyyyyyyy to frustrating. And buying & downloading popular books gets expensive since they average $9.99 to $15.99 ea., with a few free offerings and 99 cent books thrown in. Not only that, eBook sellers can zap them off your reader just as easy as you downloaded them, if they so see fit. Amazon has done it. Is it any wonder voracious readers with an eReader turn to pirated copies?
Really, I don't think libraries are in nearly as much danger from eBooks as they are from short-sighted politicians who see them as easy targets for funding cuts.
