How Collins marked a first edition
- First editions either carry NO additional printing statement on the copyright page or state "First published [Year]" — practice was not fully consistent, so confirm with jacket/ad dating
- Later printings noted with impression lines; their absence supports a first

How to verify your copy, step by step
- Find the copyright page — the verso (back) of the title page.
- Confirm the first-edition statement — look for “First Edition,” “First Printing,” or the publisher’s equivalent wording.
- Check for a number line or dated printing — the lowest number present is the printing; a dated first printing with no later printings listed is the tell.
- Verify this is the UK true first — not a later-market or reprint edition.
- Rule out a book-club edition — a blind-stamp on the rear board or a jacket with no printed price marks a book-club copy.
- Photograph four things — the front cover, spine, title page, and copyright page — the standard record for identification.
The dust jacket
For a collectible first edition the dust jacket matters as much as the book. Confirm the jacket is present and unclipped — the printed price should still be at the corner of the flap (a clipped corner or a price-less flap can indicate a book-club issue). First-state jackets can differ from later ones in the cover art, blurbs, or review quotations; where a specific first-state jacket point is known for this title it is noted above.
Binding & format
Where multiple bindings exist, the hardcover trade issue is usually (but not always) the precedence copy — confirm against the points above. Later printings often show cheaper cloth, thinner boards, or simplified spine stamping. A simultaneous signed or limited issue, when one exists, is a distinct state from the trade first.

Glossary
- First edition
- Every copy printed from the first setting of type. Collectors usually want the first edition, first printing (the true first).
- First printing / impression
- A single press run from that setting. The first printing is the earliest and most desirable; later printings are still the first edition but not the true first.
- Number line (printer's key)
- A row of numbers on the copyright page (e.g. 10 9 8 7 6 5 4 3 2 1). The lowest number present is the printing — a line including 1 marks a first printing (Random House deliberately ends at 2).
- Points of issue
- Specific physical details — a stated edition, a number line, a typo, a jacket state — that identify the true first printing.
- Book-club edition (BCE)
- A reprint made for a book club. Tells include a blind-stamped dot or square on the rear board and a dust jacket with no printed price. Not the true first.
- First thus
- The first appearance of a particular version (first paperback, first illustrated, first U.S. printing) — a first of that kind, not the first edition of the work.
