There's a wealth of information here. If you click on any of the red pins, you'll get info about the library itself and sometimes links to articles or further info.
I learned about this map from Voices for the Library, which describes itself this way:
A group of dedicated librarians and information professionals have set up Voices for the Library, a campaigning website to share positive stories from public libraries and librarians, provide factual information about library usage in the UK and draw together the fragmented responses to the many attacks on UK public library services.
This campaign is an opportunity for people to discuss why libraries and librarians are so important, and why it is vital that they are run well and serve their communities effectively.
You can also follow Voices for the Library on Facebook. It seems like a wonderful group, and even though UK culture is somewhat different from that in the US and elsewhere, I'm sure you'd find ideas that you could adapt for your own usage.
