School libraries working to support an established curriculum? This was totally normal in my high school - the texts that would be studied by a particular grade were stable for several years at a time, so they would acquire enough copies for 2 classes (60 students).

Well every book I did a report on in highschool was either provided by the school or taken out from the library. If it was a book the entire class was expected to do, we would be provided copies. If we got to choose it was up to us to get them. I was poor and couldn't buy books for school. The library always worked for me. I did alright.
