Is My Vacuum Diagrams a First Edition?

The points of issue

• UK Voyager (HarperCollinsPublishers) hardcover, 1997, ISBN 0-00-225425-5
• , subtitled Stories of the Xeelee Sequence
• The first printing carries the odd-then-even printer's key 1 3 5 7 9 10 8 6 4 2 on the copyright page
• Issued in cloth boards with a pictorial dust jacket bearing the printed price on the front flap (present on an unclipped example), the HarperCollins Voyager imprint on the spine, and the subtitle on the title page

How Voyager marked a first edition

• 1919-1921 (Harcourt, Brace & Howe): number '1' on copyright page = first printing, '2' = second, etc.
• 1921-1931: no statement on first printings; the first-edition notice (when later adopted) was simply absent, so rely on no later-printing notice.

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. Read the number line — the lowest number is the printing. A line including 1 is a first printing (Random House deliberately ends at 2). Paste it into the decoder.
4. Verify this is the UK 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?

The UK Voyager 1997 hardcover is the true first edition. The US HarperPrism trade paperback (January 1999) was the Philip K. Dick Award-eligible edition and won the award presented in 2000, but it followed the UK hardcover by about two years. This is a collection of linked Xeelee-sequence stories, not a novel.P-029341

Telling it from reprints & book-club editions

The US HarperPrism edition is the first US printing; later HarperPrism/Eos and reprint impressions are reprints. Confirm the UK first by the 1 3 5 7 9 10 8 6 4 2 number line on the copyright page.P-029342

I have a first edition of Vacuum Diagrams — what should I do?

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.
