In case you didn't already know (and for my own memory later), there has been a lot of activity in the past week or so regarding RDA. Let's see, first LC, NLM, and NAL issued their statement about the Final Report from the Working Group on the Future of Bibliographic Control (you can read it here if you haven't read it yet; it's the only place I can find it all written out fully. Which is odd.). It's been a long time coming, but it was good to see it, I suppose. They're basically saying that RDA should get published first, so that a "systematic review" can be attempted. Ok. Yawn. Apparently the implementation of RDA into the Big Three won't happen before the end of 2009, and that's assuming that all the usability testing and whatnot go smoothly.
Also, a lot of vocabulary from RDA has been coming out. I have to be honest, I've doing a lot of actual work lately, and so haven't been paying much attention to the vocabulary lists. But you should go look at them if you have the desire and/or time.
(Sometimes I wonder if the reason that these new schemas and things come out at all is because librarians are far too busy with their actual jobs to be bothered with this kind of stuff. I think I wrote a long time ago about this. I don't see how anyone gets a job where their only responsibility is to go out and make up policy for other librarians. I can't imagine any job being like that. It sounds cool, though.)
