There have been spooky happenings in the Maihaugen Gallery this Halloween. A medieval chant book, originally from the fifteenth or sixteenth century, has inexplicably transformed into a Harry Potter-inspired Monster Book of Monsters! Come see the enormous leather-and-wood-bound book complete with scary demon face, vicious teeth, and dismembered body parts. Rumor has it that the book will disappear soon after midnight on Halloween, so see it today!

While you’re in the gallery, check out the exhibit Noteworthy Connections: Music in the MIT Libraries on display until December 12, 2013.

Please note: No library users were harmed in the creation of the Monster Book, and all fun was had under the care and supervision of the Libraries’ expert Preservation team.
