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. 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. 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?

Amsterdam 1677 Latin is the true first, but it does not stand alone: the Dutch De Nagelate Schriften van B.d.S. (Glazemaker's translation, Kingma & Offenberg 25) was published simultaneously in 1677, not afterward — the editorial team delivered both copy-texts to the printer together, and scholars decline to award precedence to either. Both are collected as first editions of their respective languages; the Dutch volume omits the Hebrew grammar and is therefore not a complete counterpart. There is no contemporary English edition to compete: the Ethics did not reach print in English until 1883, when W. Hale White (Trübner, London) and R.H.M. Elwes (George Bell, Bohn's Philosophical Library) both appeared — precedence between those two within 1883 is not established by the sources consulted. George Eliot's 1854-56 English translation went unpublished in her lifetime.

Telling it from reprints & book-club editions

No book-club edition exists for a 1677 quarto. The reprint tells that matter: the work was banned in Holland in 1678 and placed on the Index in 1679, so later 17th- and 18th-century appearances are separate editions, not printings. Nineteenth- and twentieth-century scholarly editions (Paulus; Van Vloten & Land; Gebhardt) and modern anastatic/photographic facsimiles of the 1677 sheets circulate and are what donors realistically hold — a facsimile reproduces the imprint-less title page faithfully, so judge on paper, type impression and binding rather than on the title page alone.

Is the book-club edition the same as the first?

No book-club edition exists for a 1677 quarto.

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.
