volume
n.
late 14c., "roll of parchment containing writing; a bound book," from Old French volume "scroll, book; work, volume; girth, size" (13c.) and directly from Latin volumen (genitive voluminis) "roll (of a manuscript); coil, wreath," literally "that which is rolled," from volvere "to turn around, roll" (see volvox). Meaning "book forming part of a set" is 1520s in English, from that sense in French. Generalized sense of "bulk, mass, quantity" (1620s) developed from that of "bulk or size of a book" (1520s), again following the sense evolution in the French word.
