Collector terminology

Edition
A version defined by publisher, territory, format or textual change; not every reprint is a new edition.
Impression / printing
A production run within an edition. The printing line is stronger evidence than a seller’s “first” label.
First edition
Meaning depends on territory. Write “first UK edition” or “first US edition” rather than claiming a universal first.
Proof / ARC
A pre-publication copy supplied for production, bookselling or review; it is not the published first edition.
Omnibus / bind-up
Several existing works issued together. A bind-up does not add new stories merely by collecting them.
Box set
Separate volumes packaged together. Verify contained ISBNs and the product ISBN; do not confuse it with an omnibus.
Signed copy
A copy bearing a signature. Authentication requires provenance; appearance alone is not proof.
Condition
A physical description, not a price. Note jacket, boards, spine, pages, marks and repairs separately.

A publisher-series design or retail box is product data, not a new literary work. It is added only with a stable publisher entry and exact ISBNs.

How to decide whether copies differ

  1. Start with territory and imprintUK and US editions can share a title while differing in publisher, date, jacket and ISBN.
  2. Read the printing line“First published” is not enough to prove a first printing. Write down exactly what the copyright page shows.
  3. Check the textRetitles, anniversary editions, introductions and exclusive stories can change the contents.
  4. Note provenance separatelyA signature, proof stamp or bookseller description needs its own evidence; appearance alone is not authentication.
