There is nothing stopping libraries from offering Kindle versions of eBooks. I work for the Buffalo & Erie County Public Library System in the IT dept. and we do offer Kindle books. The problem, like every thing else, is that it costs money. The more proprietary eBook formats you have the higher the cost there is to stock another format for a particular book. Implementing Kindle support was also way more problematic then offering ePubs and audio books so not every library system will have the ability (or money) to do so... Personally, I think it's not really the demise of the Public Library but more the demise of our society due to the lack of proper priorities.
