Why Numbers Are Removed Rather Than Added
With each successive reprint, the publisher needs to instruct the printer to change the impression number, and the theory is that the printer is less likely to make a mistake if they are only removing the lowest number rather than introducing a new number each time. With this arrangement, all the printer has to do is "rub off" the last number in sequence. By changing only the outer number it means that the fewest possible changes are made to the page of characters, which means the smallest possible charge to the publisher. In the days of hot-metal printing, where each character was a metal block, all the printer had to do was to physically pick out the relevant blocks from the "sheet" and then the stack of blocks which would have been laboriously laid out when the page was first set up could be inked up for the reprint. In the case of a Linotype slug, the lowest number could be filed off and the slug reused. In either case, the change was minimal.

Famous quotes containing the words numbers, removed and/or added:
“Our religion vulgarly stands on numbers of believers. Whenever the appeal is made—no matter how indirectly—to numbers, proclamation is then and there made, that religion is not. He that finds God a sweet, enveloping presence, who shall dare to come in?”
—Ralph Waldo Emerson (1803–1882)
“We’ve removed the ceiling above our dreams. There are no more impossible dreams.”
—Jesse Jackson (b. 1941)
“After that came commencement day—that great day for which all other days were made. And it went. And that night I felt of myself all over, and to my astonishment, I found ‘twas the same old Rud. Not a single cubit added to my stature; not a hair’s breadth to my girth. If anything, on the contrary, I felt more lank and gaunt than common, much as if a load were off my stomach.”
—Rutherford Birchard Hayes (1822–1893)
