1. An article of manufacture, comprising:
a bound collection of leaves having a spine;
wherein each leaf of a first plurality of leaves of the bound collection includes a first pattern of tabs by which that leaf is bound, the first pattern of tabs being distributed along a binding axis of that leaf that is parallel to a spine axis of the spine;
wherein each leaf of a second plurality of leaves of the bound collection includes a second pattern of tabs by which that leaf is bound, the second pattern of tabs being distributed along a binding axis of that leaf that is parallel to the spine axis of the spine;
wherein each tab of the first pattern of tabs and the second pattern of tabs extends in a direction orthogonal to the binding axis of its leaf from within an unbound region of that leaf to a binding-side edge of that leaf, wherein each tab of the first pattern of tabs and the second pattern of tabs has a bound portion and an unbound portion in a direction orthogonal to the spine axis;
wherein the first pattern of tabs differs from the second pattern of tabs along at least a portion of the spine axis;
wherein each tab of the first pattern of tabs is spaced apart from one or more neighboring tabs of the first pattern of tabs by a gap length in a dimension parallel to the spine axis;
wherein each tab of the second pattern of tabs is spaced apart from one or more neighboring tabs of the second pattern of tabs by a gap length in the dimension parallel to the spine axis;
wherein one or more tabs of the second pattern of tabs have a tab length in the dimension parallel to the spine axis that is less than the gap length between two or more neighboring tabs of the first pattern of tabs; and
wherein the one or more tabs of the second pattern of tabs having the tab length that is less than the gap length of the first pattern of tabs are aligned within the gap length between the two or more neighboring tabs of the first pattern of tabs along the spine axis.
