On Simon & Schuster books from the mid 1970s onwards, the printing is shown by a number line on the copyright page: the lowest number present is the printing, so a first printing includes 1, even when the line is laid out out of order, such as 1 3 5 7 9 10 8 6 4 2.
Traps
- Book club copies. A jacket with no price on the front flap points to a book club edition.
- Revised editions. A 1 can appear in the number line of a revised or later edition, so check the title and copyright pages for an edition statement.
