On two occasions in different years (k and either 1st or 2nd), I had to send a message to the VP saying, effectively, please stop preventing my DD's access to literature, there's nothing in an elementary school library that should be barred to her.

This was a major problem for DD because they wouldn't let her bring any literature from home, anything she read during free time had to come from the school. And since she had a lot of free time...

Thankfully, the gifted teachers have a private library DD is allowed to access, and they're good about keeping it stocked with contemporary literature the kids are interested in, so that's a solved problem now. The only issue we had there was when one of the teachers requested a hand-written, signed note approving DD's access to Harry Potter.
