As museums shift to a service model they have a huge amount to learn from libraries. Libraries, even university research libraries, made this transition twenty years or more ago — being about access to knowledge, not just collections. They are much more tightly interwoven with their user communities and intentional about meeting the needs of those communities — and in the best cases, actively listen to weak signals from those communities and have those signals guide their strategic direction.
It has also got to do with civic funding models and a much lower influence of the super wealthy on their collections and day to day operations. This gives them a freedom and confidence to be the kind of politically aware civic institutions that our communities need them to be.
