Original fiction: A Calmer Book Exchange

The class book exchange had become confusing. Students could not tell which books were available. A sign-out sheet recorded loans. A separate basket held returned books until they were checked. Labels divided the shelves into broad topics. The new system did not make anyone read faster, but it made borrowing and returning books easier to follow.
