Leaving kids at the library

Kate Shatzkin: Last week while vacationing in my hometown of Florence, S.C., I stopped by the library for a few days and noticed that on each day there were a number of unsupervised kids present — both inside the building and outside. … I was later told that the facility had become a place where parents who can’t afford summer camp drop off their kids for the entire day, and then, to the chagrin of the library officials, are often tardy when coming to retrieve them.
