bulk

1. The thickness of the gathered leaves or sections of a book before sewing, or the thickness of the bound book before its covers are attached, or before casing-in. 2. The thickness of a sheet of paper in relation to its weight. With two papers of equal weight per ream, the one which "handles" the thicker is said to "bulk" the better. 3. The thickness of a specified number of sheets of paper or board under a specified pressure. Bulk here is important in gauging the thickness of a proposed book. 4. In papermaking in its most correct meaning, "bulk" is the ratio of fiber volume of a sheet to total volume, including air spaces which may be void or filled with loading or sizing materials.
