A book made up of pages is described. At least some of the pages contain both space for manually-created visual content, and instances of preprinted indexing target symbols. Each of the indexing target symbol instances has at least a portion within one inch of three unbound page edges. When the book is closed, the instances of each particular indexing target symbol are in a substantially collinear stack that is substantially perpendicular to the faces of the pages.

Disclosed are a system, device and method for flagging documents, wherein a Flagging Device (FD) retains one or more page flags and affixes them to the edges of a document's pages, and a Flagging Ruler (FR) detachably accepts the Flagging Device (FD) while allowing for it to travel and be positioned along its length, while accepting and holding one or more pages, to be flagged, relative to the Flagging Device FD.
