EDITION

All copies of a book printed from the same setting of type, either at one time or over a period of time, with no major changes, additions or revisions. Minor changes, such as the correction of some misspelled words, or the addition of a dedication, or similar very minor alterations, may be made and the revised copies are still considered as part of the same edition, simply being described as different states or issues. Second or subsequent editions usually involve the entire resetting of type.
