I want to refer folks over to Mylibog for an example of how a librarian responded to a parent's concern about a children's book "My Uncle Bobby's Wedding."
In Library 101 there were discussions about the rights of parents to challenge materials and library workers knowing the existing guidelines of the library in regard to challenges to books and materials.
This also touches on collection development issues raised in Library 104. One of the issues the letter brings up is can you deny services to one group while honoring others who feel offended by the material?
What are the stated policies for a patron to respond to a book that they really object to being in the library? This post is an essential read.
