Shaken and moused boards also refer to condition. Boards are the covers on a hard bound book. Moused is a vivid term indicating that the cute little critters have had a picnic - with the book forming the main course. They love the glue in the bindings. Shaken means that the pages have become partially separated from the boards.
Shaken boards are one step up from detached boards.
