I use the library a lot between my history classes and Model United Nations activities, so the library is very important to me.
I have observed that many students want to find all of their information on Internet, rather than reading print material. The challenge is in finding internet sources that contain credible research. Another challenge (not limited to information found on the computer) is getting students to interact with sources, rather than simply "cutting and pasting."
The theme of the articles on Library 2.0 seem to emphasize a synthesis of the older look of a print library with the technology offered students today.
One goal of the IB History class is to get students to take on the role of an historian. Part of that involves looking at a variety of sides or interpretations of events. One way to do that is to read books written during the 20th century. As archives are opened or additional research is conducted, new interpretations and descriptions of events are written.
Sometimes the older books give information that newer authors don't include, because of their access to newer information. (But that doesn't mean libraries should be full of "old" books only!)
For history, I think students need both a facility for using the newest technology... which many already have and they need an appreciation for books. I think there is a place for both in the Library of the future.
For me, Library 2.0 means I need to be more skilled at using Web 2.0 and Library 2.0 technology... which is why I'm taking this class! There is certainly a lot to learn.
School libraries are still needed for research and to support classroom learning. The difference between the past and now and the future is the form that the learning takes or will take.
