My parents were of the “she can read anything..go to the library, kid!” mindset.
I remember 30 some years ago when there were great debates within my own large urban library about eliminating the restriction on what kids under 12 could check out. Many staff members honestly thought they were protecting children by limiting artificially what they could read.
We moved to a system where the child’s card could be toggled on or off for for check out privileges from adult collections. The toggle was controlled by their parents. Then finally in recent years we moved to a “no restrictions at all” model and told parents it was their job to monitor their children’s checked out materials.
Looking back, these activities were quaint. Considering the thousands of god-awful sites on the Internet, all of these library materials are quite tame.
