How to verify your copy, step by step

  1. Find the copyright page — the verso (back) of the title page.
  2. Confirm the first-edition statement — look for “First Edition,” “First Printing,” or the publisher’s equivalent wording.
  3. 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.
  4. Verify this is the US true first — not a later-market or reprint edition.
  5. 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.
  6. 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?

US first, as the census claims: The Macmillan Company, New York, published February 1908, is the true first. Everett & Co., London, 1908, is the first English edition and is collected separately as a scarce edition in its own right; the sources consulted give it no month and none place it ahead of the February Macmillan, so the Macmillan holds precedence on the available evidence. Both are collected — name Macmillan (New York, February 1908) as the true first and Everett & Co. (London, 1908) as the English first. The 1917 Macmillan reissue and the many later trade, mass-market and scholarly reprints are separate editions.

Telling it from reprints & book-club editions

Reprint tells sit on the copyright page: later Macmillan impressions keep 'Set up and electrotyped. Published February, 1908.' and add dated 'Reprinted' lines beneath it, so read the full block rather than stopping at the February line — this is the single most common way a later impression is mistaken for the first. The 1917 Macmillan reissue is a separate edition. No book-club issue of the 1908 Macmillan is documented in the sources consulted.

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.
