How to verify your copy, step by step

1. Find the copyright page — the verso (back) of the title page.
2. 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.
3. Verify this is the US true first — not a later-market or reprint edition.
4. 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.
5. 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.

Is this the true first?

The US Dodd, Mead 'Murder with Mirrors' (September 1952) is the true first, preceding the UK Collins 'They Do It with Mirrors' (17 November 1952). Note the two editions carry different titles.

Telling it from reprints & book-club editions

Later Dodd, Mead and Collins printings, book-club issues, and reprints follow the respective first editions.

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.
