Definition of term:: First edition

  • All of the copies printed from the first setting of type; can include multiple printings if all are from the same setting of type. Every printed book has a first edition, many never have later editions. A later edition would have substantial changes in the printing plates or type such as the addition of a new preface or new chapter or major changes throughout the text and often is printed from a complete resetting of the type. When book collectors use the term first edition, they are usually referring to the first printing and if there are different states or issues, the earliest of those.
