They're almost exclusively open source, and they corporate across their sector to build and use the same standards, even though their management is as split up as everything else. I mean, I work in a muniplacity and we can't even agree to buy a standard component for our intranet even tough we're mainly looking for a new intranet because the old non-standardised component can't be upgraded, and meanwhile, the libraries across the country have developed and adopted universal standards for almost everything they do...
Libraries did service design and user based fail fast methods before anyone else, and I think they're still one of the few business to actually succeed at it.
They're really, really bad at marketing their successes though. Remember that movie streaming thing I talked about in the beginning? Well, almost nobody knows it exists. I bet, that none of the Danes who read this post will have ever heard about http://biblioteket.filmstriben.dk .
