Library 2.0 is an intriguing concept, one that I feel is hashed and re-hashed to death among library bloggers and the like, and bandied about in library school. It is the hip thing, the cool way to approach library services, and if you're not on the train, you'll be left in the dust. If I sound bitter, well, it's the way I sound most of the time. (Try reading Annoyed Librarian at Library Journal - she names these Library 2.0 folks 'two-point-opians'). While reading the assorted clips from OCLC on the topic, I can go along with a lot of the innovations. I have no problem with user-centered-ness, and agree that our catalogs could be a great deal more functional. I'm just futilely holding on to the library as I used to know it - I long for card catalogs and cavernous rooms full of actual books made of paper. The futurist they interviewed - when she delved into the idea of Library 3D and 4.0, my brain just shut off.
I'm also not into change for change's sake. Not all of these concepts translate perfectly to every patron or location and I think in the spirit of user-centered-ness, we should be aware of that. Not everyone will be onboard with these changes, and the library world should be patient and let change, useful change, come when it may. Maybe I just have an inferiority complex, and think I'm not cool enough for Library 2.0. I'll let that be up for debate. I'll get there, folks, it just may take some time. :)
