Abstract

See full text

A blank book attachment having a mark and sweep leaf with a fold out feature is provided. The leaf is pivotally retained along one edge on a frame, and the frame is pivotally retained at the binding spine of the host blank book. Pulling outward on the leaf causes the leaf to extend out and beyond the pages of the book allowing the pages to turn freely. When the leaf is placed within the host book, with the book open or closed, the leaf can be turned as a page, in which case it also acts as a mark to identify a specific position in the host book. Alternatively, the leaf may be pivoted on the frame to allow the host book pages to be turned past it in either direction.
