The classic Dr. Seuss book Hop on Pop appears on the annual list of books that patrons of the Toronto Public Library have asked to be removed. The reasons given? "Encourages children to use violence against their fathers." What I love about this committee's decision is this line in the summary: "The children are actually told not to hop on pop." While I think this particular request was a little loopy, I will admit that reading books to my kids has raised issues that I never thought I would worry about in the past. Reading the Little House on the Prairie books, which I adored growing up, I've struggled with whether to stay true to the text and discuss both land rights and prejudice against people of the First Nations, or skip those chapters (or that book.) I eventually decided that the original Bobbsey Twins books in my parents' attic just plain were not worth trying to sort out. I would never suggest that these books should be banned at the library, but for our family we do sometimes pull things off the shelves. What's your book-vetting strategy?
