NOMENCLATURE OF SHEETS.
When a sheet of paper of Medium or larger size is folded in two leaves, like most newspapers, it is called a folio; when folded in four leaves, it is named a quarto or 4to; when folded in eight leaves, an octavo or 8vo; in twelve leaves, a duodecimo or 12mo; in sixteen leaves, sextodecimo or 16mo; in eighteen leaves, octodecimo or 18mo; in twenty-four leaves, vigesimo-quarto, or 24mo, and so on. The Latin names beyond duodecimo are seldom used.
Abstract Title-Deeds of Estates.
Abstract Title-Deeds of Estates are printed with blanks at the back, with all the margin on the left side, and on single leaves, which are stitched together at the corner.
This method of imposing the form is to save presswork and the compositor’s charge.

Imposing in quires may be carried to any extent, by observing the following rule:—first ascertain the number of pages, then divide them into so many sheets of folio, and commence laying down the first two and last two, which form the first sheet, and so on to the centre one, always remembering that the odd pages stand on the left and the even on the right; the folios of each two forming one more than the number of pages in the work: for example, let us suppose the work to consist of thirty-six pages, which is nine sheets of folio, then they should be laid down according to the scheme at the foot of the opposite page.
Two Sheets of Folio, Quired, or lying one in another.

The white paper of this half-sheet being worked off, the centre pages must be transposed,—viz. pages 7 and 10 in the room of 9 and 8, and pages 9 and 8 in the place of 7 and 10: when this is done, your imposition will be true.
