THE ART OF BOOKBINDING.
We commence with folding. It is generally the first thing the binder has to do with a book. The sheets are either supplied by the publisher or printer (mostly the printer); should the amateur wish to have his books in sheets, he may generally get them by asking his bookseller for them. It is necessary that they be carefully folded, for unless they are perfectly even, it is impossible that the margins (the blank space round the print) can be uniform when the book is cut. Where the margin is small, as in very small prayer books, a very great risk of cutting into the print is incurred; besides, it is rather annoying to see a book which has the folio or paging on one leaf nearly at the top, and on the next, the print touching the bottom; to remedy such an evil, the printer having done his duty by placing his margins quite true, it remains with the binder to perfect and bring the sheet into proper form by folding. The best bound book may be spoilt by having the sheets badly folded, and the binder is perfectly justified in rejecting any sheets that may be badly printed, that is, not in register.
