A group of librarians from Waupaca, Wisconsin are posing nude for a "Desperate Librarians" calendar in an effort to raise money for local libraries.

Large library books are strategically placed to cover intimate places. While the models appear naked, they are wearing special cover-ups during the photo shoot.

The oldest volunteer model is library director Lucie Erickson, who turned 60 last month and organized the "Desperate Librarians" fundraiser.
