A money quote:
as a little girl I would cut out construction paper pockets, glue them into books at home, and print as carefully as I could on them: “for reverance [sic] only – not to be taken from this room” … Any librarian still reading this far: Please: I meant that then, and I still do. I understand the pressures that you are under to cull collections and make space. But don’t purge too many books too quickly from the library.
