Martin Lewis has produced a guide for organisations wanting to provide warm spaces:
This guide is the culmination of that. I asked CILIP to research and collate best practice information, on how to do it, and I am delighted that they accepted the commission. It’s not just for libraries, it’s for any organisation wanting to set up a warm space (the name has rightly changed too, a warm space is a far more approachable place than a warm bank). I do hope you find it useful.
