Edition (book)

The bibliographical definition of an ion includes all copies of a book printed “from substantially the same setting of type,” including all minor typographical variants.

The numbering of book ions is a special case of the wider field of revision control. The traditional conventions for numbering book ions evolved spontaneously for several centuries before any greater applied science of revision control became important to humanity, which did not occur until the era of widespread computing had arrived (when software and electronic publishing came into existence). The old and new aspects of book ion numbering (from before and since the advent of computing) are discussed below.

First ion[]

According to the definition of ion above, a book printed today, by the same publisher, and from the same type as when it was first published, is still the first ion of that book to a bibliographer. However, book collectors generally use the term first ion to mean specifically the first print run of the first ion (aka "first ion, first impression"). Since World War II, books often include a number line (printer's key) that indicates the print run.

A "first ion" per se is not a valuable collectible book. A popular work may be published and reprinted over time by many publishers, and in a variety of formats. There will be a first ion of each, which the publisher may cite on the copyright page, such as: "First mass market paperback ion". The first ion of a facsimile reprint is the reprint publisher's first ion, but not the first ion of the work itself.

The Independent Online Booksellers Association has a A First Edition Primer which discusses several aspects of identifying first ions including publishing and specific publishers way of designating first ions.

Bibliographical definition[]

The classic explanation of ion was given by Fredson Bowers in Principles of Bibliographical Description (1949). Bowers wrote that an ion is “the whole number of copies printed at any time or times from substantially the same setting of type-pages,” including “all issues and variant states existing within its basic type-setting, as well as all impressions.”

Publishers often use the same typesetting for the hardcover and trade paperback versions of a book. These books have different covers, the title page and copyright page may differ, and the page margin sizes may differ (same type area, smaller trim), but to a bibliographer they are the same ion.

From time to time, readers may observe an error in the text (or, in the days of metal type, a piece of broken type), and report these to the publisher. The publisher typically keeps these "reprint corrections" in a file pending demand for a new print run of the ion, and before the new run is printed, they will be entered.

The method of entry, obviously, depends on the method of typesetting. For letterpress metal, it typically meant resetting a few characters or a line or two. For linotype, it meant casting a new line for any line with a change in it. With film, it involved cutting out a bit of the film and inserting a new bit. In an electronic file, it means entering the changes digitally.

Such minor changes do not constitute a new ion, but introduce typographical variations within an ion, which are of interest to collectors.

Collectors' definition[]

A common complaint of book collectors is that the bibliographer's definition is used in a book-collecting context. For example, J. D. Salinger's The Catcher in the Rye as of 2016 remains in print in hardcover. The type is the same as the 1951 first printing, therefore all hardcover copies are, for the bibliographer, the first ion. Collectors would use the term for the first printing only.

First ion most often refers to the first commercial publication of a work between its own covers, even if it was first printed in a periodical: the complete text of Ernest Hemingway’s The Old Man and the Sea appeared in the September 1, 1952 issue of Life, yet the generally accepted “first” ion is the hardcover book Scribner’s published on September 8, 1952.

The term "first trade ion," refers to the earliest ion of a book offered for sale to the general public in book stores. For example, Upton Sinclair's 1906 novel The Jungle was published in two variant forms. A "Sustainers' Edition", published by the Jungle Publishing Company, was sent to subscribers who had advanced funds to Sinclair. The first trade ion was published by Doubleday, Page to be sold in bookstores.

Many book collectors place maximum value on the earliest bound copies of a book—promotional advance copies, bound galleys, uncorrected proofs, and advance reading copies sent by publishers to book reviewers and booksellers. It is true that these are rarer than the production copies; but given that these were not printed from a different setting of type (just the opposite; the main purpose of galleys and proofs is to double-check the typeset matter that will be used for production), they are not different ions.

Publishers' definitions[]

Publishers use "first ion" according to their own purposes, and consequently among them the designation is used very inconsistently. The "first ion" of a trade book may be the first iteration of the work printed by the publisher in question or the first iteration of the work that includes a specific set of illustrations or orial commentary.

Publishers of non-fiction, academic works, and textbooks generally distinguish between revisions of the text of the work, by typically citing the dates of the first and latest ions of the work in the copyright page. Exceptions to this rule of thumb include denominating as a "second ion" a new textbook that has a different format, title, and/or author(s) because a previous textbook that shares only the same subject matter as the "second ion" is considered the first ion. The reason for this stretch of the definition is often for the short-term marketing advantage of the new textbook, because, although first ions are often considered more valuable than later ions to book collectors, being a subsequent ion of a previous textbook gives the impression that the textbook denominated as a subsequent ion is more authoritative.

Other types of ions[]

Revised ion[]

Publishers sometimes denominate a new iteration of a work a "revised ion" or the "(N)th ion, revised" when the previous iteration has been orially revised or updated yet the author or publisher does not want to denominate it the "(N+1)th ion" ("N" being the number of the previous ion) for some subjective reason. Conversely, a new iteration of a work that is not substantially different may be denominated a "new ion" or the "(N+1)th ion".

The qualitative difference between a "revised ion" and a "new ion" is subjective. This is analogous to the way that software publishers may denominate an iteration "version 3.7" and the subsequent updated iteration "version 4" instead of "version 3.8". The subjective judgment of the degree of the significance of the change made with the new iteration or the perceived marketing advantage of designating the new iteration as a specific number determines how the new iteration is numbered.

Therefore, the designation "revised ion" does not designate any quality or quantity of revision with certainty.

Revised and updated ion[]

When a non-fiction book is first published it sometimes instigates more research on its subject. The author may determine that new information justifies the revision of the book. A new iteration of the book would be published as a new ion, which may be denominated a "revised and updated ion". However, as with the denomination of "revised ion", the use of "revised and updated ion" manifests only the subjective choice of the publisher, which may be different from the publisher of a previous "revised ion" of the same work.


The basic definition of a co-ion is when two publishing houses publish the same ion of a book (or equivalent versions of an ion, for example, translated versions), simultaneously or near-simultaneously, usually in different countries. English and American ions may differ in spelling, and they sometimes have different titles. Some examples:

The motivation for co-ions has often been to use the existing distribution systems of the different publishers in each country rather than establishing new distribution systems.

Advancing IT and the globalization of publishing have been blurring the lines of what co-ion means. For example, anything published online is effectively published worldwide. Also, large multinational publishers now have existing distribution systems for their hardcopy books in many countries, so they don't need to partner with other companies. They may issue a book under a different imprint for each country, but the imprints are parts of the same parent corporation. The actual manufacturing of the books may be done in China regardless of where the copies will be sold.


The term e-dition, a play on the e-for-electronic prefix, has been used by various publishers to refer to various ideas, which include:

Library ion[]

A library ion may appear to be the same as copies appearing in shops and almost certainly uses the same setting. However, the binding and hinges are made extra strong to allow for the greater wear and tear in library books. This is analogous to the "police and taxi" packages for automobiles, in which heavier brakes and other upgrades are made to withstand harsher-than-standard use and longer duty cycles.

Book club ion[]

A popular book is sometimes re-issued under the imprint of a book club. Often it is a new setting and with cheaper paper and binding. Any photographic illustrations in the original are either absent or reduced in number. Book club ions are sold to members at a good discount compared with the original issue price.

Cheap ion[]

After a book has exhausted the market at the high original price a publisher may issue a cheap ion themselves or sell the rights on to another publisher who will produce the book. A cheap ion typically uses a low-cost paper and is a paperback but they can be hardback. Also typically the size of the font is reduced to fit more words on a page to reduce the overall cost of the book. Naturally, for a cheap ion the author will receive a lower royalty but that may be compensated for by a greater volume of sales.

Colonial ion[]

During the peak of the British Empire, cheap ions of novels published in Britain would often be produced for sale in the colonies before other ions of the books were sold. The rationale was that books took a long time to export to the colonies, that readership in those settlements was avid, and that books were an effective means to disseminate British values. Australia was by far the largest consumer of colonial ions. Macmillan (London) published the largest number of colonial ion titles. They began in 1843 and persisted (in terms of pricing and trade) until the 1970s.[2]

Cadet ion[]

A cadet ion is a cut down version of a book which is more simply written. It is intended for young readers rather than adults.

Large print ion[]

These ions are typically library ions but the font size of the text is much larger than usual so that persons with poor eyesight (often older persons) can more easily read the book. The large print books tend to be of a uniform size.

Critical ion[]

A critical ion is a scholarly publication, containing commentary, critique, and sometimes a full developmental history of the work from all available sources.

Printing, print run, impression, et cetera []

A batch of identical copies of an iteration/ion of a work that is printed in the same, single execution of the production set-up is denominated a "print run", "printing run", "printing", "impression", or "press run" according to the subjective choice of the publisher. All these denominations denote the action of applying pressure to paper in order to produce the book, and therefore are interchangeable. One ion of a work may have any number of printings, e. g. first ion, first impression; first ion, second impression; and second ion, first impression. Books that sell poorly may have only one. Very successful books may have 50 or more. If present, the printer's key in the copyright page of a book can be used to identify the number of the printing in which it was produced. In printmaking, however, an "impression" only denotes an individual copy of a specific printing of the work. A publisher hopes to recoup a large amount of the initial costs of publishing a book from the sale of the copies/impressions produced in the first printing of the book. A variety of commercial and logistic factors are thus considered in deciding the number of books to be produced in a specific printing and their individual price.

Demand for additional printings after the first is always hoped for, because they increase a book's profitability. Once the fixed costs of developing, ing, typesetting, etc. have been covered by the revenue of the first sales, any additional revenue tends to add to the profit margin, minus, of course, the costs of the additional materials, printing, binding, and distribution.

Sometimes a printing will be unsatisfactory for various reasons, especially printings of artistic and photography books in which the quality of reproduction is paramount. A defective printing is usually destroyed by being pulped, yet occasionally a defective printing is shipped to a distant overseas market and there sold cheaply, contingent on the costs of shipping.

If sales of a book do not meet expectations, the remaining stock of a printing will be remaindered. When all copies/impressions of a printing are sold, the book is either reprinted or becomes out of print. Some print on demand and e-book publishers keep all their books perpetually "in print".

A "second" is an imperfect or damaged copy/impression which is set aside from the other copies/impressions of a printing. These will usually have their dust jacket clipped or marked in some way to designate their inferiority.

Sometimes readers may observe an error in the text of a book and report it to the publisher. The publisher usually records these reprint corrections in a file pending demand for a new printing, before which they are incorporated into the revised text. This is one of the factors that inserts the "substantially" into the definition of "substantially the same setting of type".


Many commercially successful books have been republished, either by their original or other imprints. For this reason if a popular book is searched for in a large bookseller such as Amazon.com or a large library catalog such as WorldCat, often an array of different copyright years, publishers, ions, formats (hardcover, softcover, trade, and mass market), and so forth are observed. Because no universal authority or convention determines the exact distinction between a "reprinting" and "republishing" and whether a republishing is a different "ion", the denotation of such denominations is ambiguous, at least at first glance.

Legal status[]


Since 1956, typographical arrangements of published ions are protected by copyright law. Copyright, Designs and Patents Act 1988 defines a published ion to mean a published ion of the whole or any part of one or more literary, dramatic or musical works.[a]

It thus protects the publisher's investment in typesetting, as well as the processes of design and selection that are reflected in the appearance of the text.[b] It also covers modern ions of public domain works (such as the complete works of Shakespeare), and prohibits the reproduction of the layout (but not the work itself).
