Swear to god, I really, really thought that the link at Bookslut was heading to an article at the Onion.
From The Book Standard:
After discovering that renowned children’s-book author and publisher Harriet Ziefert’s latest book, A Snake Is Totally Tail, is strikingly similar to Judi Barrett’s 1983 book of the same name, publisher Blue Apple has announced that it will not be releasing the version authored by Ziefert, originally set for release in April.
GAH. If you can't trust Harriet Ziefert, who can you trust?
