We might never know whether or not someone was pulling a prank. However, because the complaint was filed and TPL considered it the Dr. Seuss title is now included on the Toronto Public Libraries official list of materials asked to be reconsidered.
From CTV News:
A popular tale by Dr. Seuss was one of seven books that patrons have asked Toronto Public Library to remove from its collection over the past year.
A library patron asked the library’s materials review committee to pull “Hop on Pop,” a children’s classic written in 1963, because of the book’s violent themes.
The complainant said the book encouraged children to use violence against their fathers, according to the document that listed books patrons have asked to be pulled from Toronto Public Library shelves, which was posted online Monday.
But the committee decided that the book was designed to engage children, and that the story actually advises children against hopping on their fathers.
The CTV report (and video) list other books that people asked to have removed from TPL’s collection during 2013.
