a book open and partly stuck in another book, keeping place in both books. one of the books ie hemlock and silver by t kingfisher and the other is tolkein's personal translation of beowolf which is okay but only okay, but then, he never really intended to publish it it was mostly for his own notes so on that basis it's pretty good (and you can really tell where he really worked it for his own purposes, too)
