Hi code4libbers! As part of my work on Open Library, I've been doing what I expect a lot of you find yourself doing: collecting big batches of MARC records, testing algorithms for processing them, building interesting ways to visualize them. And what I've found is that while the community of other people doing this in libraries is really valuable, I also have a lot to learn from people who do this sort of thing with other types of data. So I'm trying to build a code4lib-style community around people who work with large data sets of all kinds: http://theinfo.org/ I hope that you'll take a look and join the mailing lists and get involved. I think that there's a lot we could do together.
