We gained a tremendous amount of production efficiency, slashing the time it takes to go from manuscript to press. I recall working five months in advance to ensure that I had adequate time for the entire process: 2 weeks to edit a new paper, 3 weeks to get queries answered by the author and obtain their final approval, and 1 to 2 weeks for the typesetters to send back galleys (through regular mail or UPS, of course!).
