In my opinion, all of the perspectives from the OCLS Next Space Newsletter point towards the library on-line sites (Web sites) - rather than the library buildings themselves being the focus point of the majority of its users.
Librarians of the future will need to be trained tour guides. Whether they are answering questions on line or on the floor.
Whichever chair they are sitting in - they will be guiding the future users through all the aspects of finding the information they want.
There will be a need for the print collection but how much and in what format will be the questions on Acquisitions and Collection Management Librarians' minds.
