Tempscire, as you so...aptly put it, the people that do the job a lot of high schoolers could handle are called Pages, not Library Clerks. And most of the time the Pages -are- high schoolers. A Library Clerk, on the other hand, handles everything from book repair to coding to database entry across multiple software programs just to start. They also get to handle the disgruntled patrons the desk clerks can't handle and supervise the staff. It's not a job any high-schooler could do.
