Yes. Circulation and computer usage stats keep the branches open and drive staffing budgets (along with political skill of management, of course). Staff may be overworked and grumpy, but they do derive immense satisfaction and their livelihood from helping patrons find what they need and seeing them come through the doors for any reason other than to complain. When my wife worked at a busy little branch in Oakland, all of these things were frequent topics of dinner conversation.
I'm not sure if this counts in the same way, but I'm a huge user of inter-library loan; large city systems HAVE the obscure computing and other books I want to read, but there's no way each little branch can.
