1st Edition NASA Tech Briefs

Publishers of non-fiction, academic works, and textbooks generally distinguish between revisions of the text of the work, by typically citing the dates of the first and latest editions of the work in the copyright page. Exceptions to this rule of thumb include denominating as a “second edition” a new textbook that has a different format, title, and/or author(s) because a previous textbook that shares only the same subject matter as the “second edition” is considered the first edition. The reason for this stretch of the definition is often for the short-term marketing advantage of the new textbook, because, although first editions are often considered more valuable than later editions to book collectors, being a subsequent edition of a previous textbook gives the impression that the textbook denominated as a subsequent edition is more authoritative.
