License to ILL! I love it.
Sure, in public libraries you can ask for anything.
I used to do ILL work in a research library and there, things could get complicated because some libraries charged, some didn't and others worked on a voucher system.
We were an art library and, through the old RLIN system, we could receive ILLs from other art libraries without charge. We got a nasty surprise when a loan we thought would be free arrived with a bill for 55USD.
