myliblog: "Uncle Bobby's Wedding" Challenge
I recently came across a letter written in 2008 by Jamie LaRue (the director of the Douglas County Libraries) in response to a book challenge. (BTW, I recommend reading both the letter and the many replies to Jamie's post.) His blogpost is a tremendous example of how to repond: clear, reasoned, acknowledging the patron's concern while carefully explaining the rationale for the title in question.
I will definitely be following his blog!
