How to tell if a book is a first edition

Here is how to tell if a book is a first edition, step by step. Most of the answer is printed on one page: the back of the title page. You also need to know a few traps, such as book club copies and publishers who kept the words “First Edition” in later printings.

Edition, printing, impression: what collectors mean

An edition is all the copies printed from the same setting of type. A printing (or impression) is one press run of that edition. When collectors say “first edition”, they almost always mean the first printing of the first edition: the very first copies sold.

A “true first” is the first appearance of the text as a book anywhere. For example, Moby-Dick first appeared in London as The Whale on 18 October 1851, almost a month before the New York edition.

1. Read the copyright page

Turn to the back of the title page. Look for statements like “First Edition”, “First Published in 1997” or “First Printing”. Check that the date matches the date on the title page, and that no later printings are listed (for example “Second impression” or “Reprinted 1998”).

2. Read the number line

Many modern books print a row of numbers on the copyright page, called the printer’s key or number line. A common style is 10 9 8 7 6 5 4 3 2 1. Each time the book is reprinted, the lowest number is removed. So if you can see a 1, it is usually the first printing. If the lowest number is 2, it is the second printing.

Publishers differ. Some never used a number line, some used letters, and some kept a “First Edition” statement while the numbers changed. When the statement and the number line disagree, trust the number line and check a guide for that publisher.

3. Rule out book club editions and facsimiles

Book club editions often look like first editions but are worth far less. The Independent Online Booksellers Association lists the usual signs:

  • No price printed on the dust jacket flap (but art books, university press titles and textbooks often lack one too).
  • A small blind stamp, a pressed mark with no ink, near the bottom right of the back cover: a dot, circle, square, star or maple leaf.
  • A smaller size and cheaper paper than the publisher’s own edition.
  • A short code of numbers and letters printed near the gutter of a back page.

Facsimile dust jackets, which are modern copies of rare jackets, are common too. Many are marked as facsimiles on the flap or inside.

4. Check the points of issue

Points of issue are small details found only in the first printing: a misprint, a missing word, a different binding colour. Collectors use them when the copyright page is not enough. Bibliographies for each author list them, and reference books such as Bill McBride’s A Pocket Guide to the Identification of First Editions explain the rules used by many publishers.

Example: Harry Potter and the Philosopher’s Stone

Bloomsbury published the first Harry Potter book in June 1997 with a first hardback print run of 500 copies, about 300 of which went to libraries. That is why the first printing is so sought after. Sotheby’s lists the checks collectors use:

  • Bloomsbury named at the foot of the title page, and 1997 as the only date on the copyright page.
  • The number line 10 9 8 7 6 5 4 3 2 1.
  • “1 wand” listed twice in the list of school equipment.

The name “Joanne Rowling” on the copyright page is not proof by itself: it appears in British editions until September 1999. Many later printings exist, so check every point before you get excited.

Older books: before number lines

Books from the 1800s rarely say “first edition”. Instead, compare the date on the title page with the year the book was first published, and check the publisher and the number of volumes. Many Victorian novels first came out in three volumes: Jane Eyre (Smith, Elder and Co., 1847) and Great Expectations (Chapman and Hall, 1861) are examples. A one-volume copy with a later date is a later edition.

Frequently asked questions

Does “First Edition” on the copyright page mean it is a first printing?

Not always. Some publishers kept the words “First Edition” in later printings and only changed the number line. Check the number line and any points of issue.

What does 10 9 8 7 6 5 4 3 2 1 mean in a book?

It is the number line, or printer’s key. The lowest number shows the printing, so a line that still includes 1 usually means a first printing.

Are book club editions worth anything?

Usually very little to collectors, because they were printed in large numbers and are not the publisher’s first printing. They are fine reading copies.

Is every first edition valuable?

No. A first edition is valuable only if collectors want that book. Condition, the dust jacket and signatures matter a lot too.
