Digital Technology and Copyright

Just finished my essay for Double Fold. It makes me think about technology and all of its applications concerning information and libraries, etc. I wasn't aware before how much copyright and ownership of ideas are debated between publishers and libraries. In Sarah Thomas's article from "Double Fold to Double Bind" she shows how publishers are now considering holding back distribution of digital literature (if I am remembering this correctly) in order to be able to maintain rights to these books. It seems this creates an entirely new dillema for libraries in that they now may not even have access to these books. Hard copies will always exist I hope but if publishers plan to only publish certain books electronically, does this greatly diminish the role of the library? I am just trying to sort this out through the blog. Hope to understand more of this soon...
