Abstract: A printable divider is formed from a stock sheet having a binder edge and a plurality of free edges. A folding tab is formed within the stock sheet proximate one of the plurality of free edges, and folds along a fold line from a first position, wherein the folding tab lies within the boundaries of the stock sheet as defined by the binder edge and plurality of free edges, to a tab position, wherein a portion of the folding tab extends beyond the boundaries of the stock sheet. In a particular embodiment, with the folding tab in the first position, the boundaries of the stock sheet are such that the stock sheet may be fed through a standard printing apparatus of the type that prints upon stock sheets having substantially straight edges.
