About this book
The 979 prefix was introduced when the 978 range approached exhaustion. Because the ten-digit format has no room for it, a 979 ISBN simply has no ISBN-10 form.
This book surveys the consequences for catalogue software that stored a ten-digit column as the primary key, and documents the migration strategies that worked.
