Numbering bound books is more difficult than numbering sheets, and may be done by machine only where the figures are to be located at the top corner of the leaves.
If the numbers must be located elsewhere, the book is numbered before binding. Numbering before binding may be done either as a separate operation in the bindery after the sheets have been ruled or printed, or on the printing press by means of a numbering machine in the form, a process called "numbering at press."
Sheets on which the same number appears two, three, or more times are described as double-numbered, triple-numbered, etc., while sheets on which the same number repeats on more than one sheet are described as being numbered in duplicate, triplicate, etc.
Numbering machines may be designed to impress the same number over and over, consecutive numbers, or, in the case of the skip-wheel numbering machine, may omit numbers as desired. (264 , 320 )
