Community libraries I've been in touch with have sourced books from wide range of places.
In terms of bulk buying, I know that some have had discussions with wholesale companies like Betrams. Mike McCusker at Fresh Horizons has a conversation with them and they were open to the idea of offering a group discount if a number of community libraries wanted to join up as a a buying group. He was in touch with Neil Barker, Northern Account Manager
