Libraries and library collections are evolving. Formats are changing as technology advances, and physical libraries are expanding into an ever increasing digital world. Acquiring more materials in several different formats, including electronic brings on the issue of what to do with it all. Anyone, or any entity, that collects books in print or electronic format will eventually come to the realization that their space is finite. In order to acquire new materials they must either expand their space or do that horrible "four letter word"... weed. The word itself sends shivers down the backs of librarians everywhere. How can any self-respecting librarian get rid of precious materials? If money was no issue libraries everywhere would continue to build or acquire additional virtual storage space to avoid discarding something that may be valuable to some user sometime in the future.
