kingpaul said:I live in Erie County in PA. I can borrow a book from any library that is either a) a part of the Erie County Library system or b) a library that has put their catalog listing into the Erie County Library catalog system. Frex, I live in Girard, but Girard's library is not a County library. However, their catalog is in the County's system, so its one card.
Also, there's a system called AccessPA, which is basically a PA-wide inter-library loan system. If my libraries don't have a book, I can request to borrow from a library in PA that does have it.
EricNoah said:I believe the libraries in my area are municipal but fortunately they cooperate as part of one South Central Library System. These libraries have a union catalog and provide inter-library loaning throughout the system. It's pretty remarkable. I can have any material from any branch/member library delivered to any other branch for pickup.
Here's a map that shows the scope of SCLS -- it covers seven counties (note that Madison alone has about 9 branches):
