That's been my concern, too, Chas. Supposedly libraries will be able to choose to automatically order more "copies" in response to large request volumes for particular titles. And maybe libraries will devote more of their budget to ebooks withe the kindle influx.
But we all know that most libraries are strapped. So more copies of titles (that will now "expire after x number of checkouts") will have to equate to less total titles in all.
Gonna be interesting. Glad I have a huge backlog of stuff to read anway.
