The points of issue

Decode the printer’s key: paste the number line into the decoder.

How to confirm the first-printing statement

Publishers stated first printings differently by era. The decisive tells are a printed “First Edition/First Printing” statement, a number line whose lowest number is 1 (Random House ends at 2), or a dated first printing with no later printings listed. Paste your copyright page into the number-line decoder.

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. 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.
  4. 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 Senate document (No. 174) precedes and is more complete than the House document (No. 166); both appeared in 1845, but the Senate issue is the form treated as the true first.P-035266

Telling it from reprints & book-club editions

D. Appleton & Co. issued a commercial trade reprint of the report as early as 1846 under the altered title "Narrative of the Exploring Expedition to the Rocky Mountains...," dropping the Senate document's astronomical and meteorological tables and the congressional-document format; this and similar commercial reprints from other publishers in the years that followed should not be mistaken for either 1845 congressional issue.P-035267

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.
