Sections (p. [102]).—A section, or “gathering,” commonly consists of four book-sheets, folded in half into eight leaves (i.e. sixteen pages), but three or even two sheets are sufficient when they are extra thick, and five or six may be used when extra thin. Parchment sheets should have their smooth sides so placed together that each “opening” of the book has both its pages rough or both smooth and the pages are pounced after they are ruled (see p. [174]).
Before the writing is begun the pages of the section are numbered on the inner marginal line, [p111] about 12 inch or so below the footline. This will prevent mistakes.
Fly-leaves.—One or more leaves of the first and last sections in a book are left blank (besides the extra sheet or section (p. [346]) which is used in the binding—attached to the cover). A book of any size or importance ought to have at least three fly-leaves at the beginning, and three or four at the end. These extra leaves protect the manuscript, and, in a sense, constitute margins for the whole body of the text. They may also be used to make thin books thicker, for the sake of the binding. At the end of Service books, or other books likely to be of permanent interest, additional fly-leaves should be provided for notes and annotations (see pp. [344], [346]).
Rough or Smooth Edges.—The rough “Deckle” edges of hand-made paper are inconvenient in a book of any thickness, and should be trimmed off after folding, though they may be left in the case of very thin books. The deckle edge should not occur at the top of the page, as it would there be a trap for dust, and because it is important that the tops of pages should all be level. The top edge or head of a book is often cut and gilt in order to keep out the dust—this is called “Library gilt.” It is more suitable, however, that all the edges be gilt.
The Top Margins throughout the book are kept quite level. Any irregularity at the top of a page catches the eye at once, while slight differences at the side, or considerable differences at the foot, may occur without spoiling the appearance of the margins. All measurements for marginal and writing lines, &c., are therefore made from the [p112] fold of the book-sheet and from the top edge, which is cut at right angles to the fold.
Regular Writing.—In writing one page it is a good plan to have its fellow page, or a similarly written one, fixed on the desk beside it as a pattern. This will save the beginner from a very common error—writing larger or smaller (which of course spoils the look of the pages).
Initial Page.—The text of a book commonly begins on a recto, or right hand, page (see p. [365]).
