Is My The Case of the Sleepwalker's Niece a First Edition?

The points of issue

• First published by William Morrow, New York, 1936 (the eighth Perry Mason novel)
• No number line; the first printing shows 1936 on the title page with no later-printing statement on the copyright page
• Black cloth, titles stamped in red, red top stain

How William Morrow and Company marked a first edition

• Pre-1973: usually printed 'First Printing (Month, Year)' on the copyright page and ALWAYS indicated later printings — so a first shows only the first-printing notation.

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 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 Morrow edition is the true first for this American author.

Telling it from reprints & book-club editions

Later Morrow printings and reprint editions follow; identify the first by the title-page year and absence of a later-printing notice.

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.
