3M was one of the big hits of ALA -- an alternative to Overdrive. As it happens, DCL had a lot to do with this product, as in pretty much defining the goals, doing the mock-up of how it should work, getting it to directly integrate with our catalog, and more. Major kudos here to Monique Sendze, my Associate Director of Information Technology, and her staff.
I spoke with Eric Hellman at ALA about it, and he wrote a nice blog post here. He's a smart guy.
