Encyclopædia Britannica
The Encyclopædia Britannica , published by Encyclopædia Britannica, Inc., is a general knowledge English-language encyclopaedia that is available in print, as a DVD, and on the Internet. It is written and continuously updated by about 100 full-time editors and more than 4,000 expert...

 has been published continuously since 1768, appearing in 15 official editions. Several editions have been amended with multi-volume "supplements" (3rd–6th) or undergone drastic re-organizations (15th). In recent years, digital versions of the Britannica have been developed, both online and on optical media. Since the early 1930s, the Britannica has developed several "spin-off" products to leverage its reputation as a reliable reference work and educational tool.

Historical context

Encyclopedias of various types had been published since antiquity, beginning with the collected works of Aristotle

Most early encyclopedias did not include biographies of living people and were written in Latin, although some encyclopedias were translated into English, such as De proprietatibus rerum (On the properties of things) (1240) by Bartholomeus Anglicus.

Although not all encyclopedias succeeded commercially, their elements sometimes inspired future encyclopedias; for example, the failed two-volume A Universal History of Arts and Sciences of Dennis de Coetlogon (published 1745) grouped its topics into long self-contained treatises, an organization that likely inspired the "new plan" of the Britannica. The first encyclopedia to include biographies of living people was the 64-volume Grosses Universal-Lexicon (published 1732–1759) of Johann Heinrich Zedler

By releasing the numbers in weekly installments, the Britannica was completed in 1771, having 2,391 pages.

The key idea that set the Britannica apart was to group related topics together into longer essays, that were then organized alphabetically. Previous English encyclopedias had generally listed related terms separately in their alphabetical order, rather like a modern technical dictionary, an approach that the Britannica's management derided as "dismembering the sciences". Although anticipated by Dennis de Coetlogon, the idea for this "new plan" is generally ascribed to Colin Macfarquhar

The vivid prose and easy navigation of the first edition led to strong demand for a second. Although this edition has been faulted for its imperfect scholarship, Smellie argued that the Britannica should be given the benefit of the doubt:
Smellie strove to make Britannica as usable as possible, saying that "utility ought to be the principal intention of every publication. Wherever this intention does not plainly appear, neither the books nor their authors have the smallest claim to the approbation of mankind".

Compared to the 1st edition, the second had five times as many long articles (150), including "Scotland" (84 pages), "Optics" (132 pages), and "Medicine" (309 pages), which had their own indices. The second edition was published in 181 numbers from 21 June 1777 to 18 September 1784; these numbers were bound into ten volumes dated 1778–1783, having 8,595 pages and 340 plates again engraved by Andrew Bell.

The long period of time during which this edition was written makes the later volumes more updated than the earlier ones. Volume 10, published in 1783 after the Revolutionary War was over, gives in the entry for Virginia: "Virginia, late one of the British colonies, now one of the United States of North America..." but the entry in Volume 2 for Boston, published in 1778, states, "Boston, the capital of New England in North America, ....The following is a description of this capital before the commencement of the present American war."

The 4th edition was begun in 1800 and completed in 1810, comprising 20 volumes with 16,033 pages and 531 plates engraved by Andrew Bell. The editor was Dr. James Millar, a physician, who was good at scientific topics but criticized for being "slow & dilatory & not well qualified". The mathematical articles of Prof. Wallace were widely praised in the 4th edition but, overall, the 4th edition was a minor revision of the 3rd, updated in its historical and biographical articles.

The copyright of the material in the supplement to the 3rd edition was owned by Thomas Bonar

Bonar was friendly to the article authors, however, and conceived the plan of paying them as well as the article reviewers, and of allowing them to retain copyright for separate publication of their work.

5th edition

After Andrew Bell died in 1809, his heirs botched the fifth edition; the dilatory and unqualified Dr. Millar was again the editor. Completed in 1817, the fifth edition sold for 36 pounds sterling (2011: £) and consisted of 20 volumes with 16,017 pages and 582 plates.

, an apprentice bookseller, who had been involved in its publication from 1788. To secure the copyrights for the 3rd edition supplement, Constable gave Bonar a one-third stake in the Britannica; after Bonar's death in 1814, Constable bought his rights to the Britannica for 4,500 pounds sterling.

Supplement to the 5th edition

After securing sole-ownership rights in December 1816, Constable began work on a supplement to the 5th edition, even before the 5th edition had been released (1817). The supplement was completed in April 1824, consisting of 6 volumes with 4933 pages, 125 plates, 9 maps, 3 "dissertations" and 160 biographies, mainly of people who had died within the preceding 30 years. This edition was the first to have an Index listing the 669 articles.

The 11th edition retained the high scholarship and eminent contributors that marked the 9th edition, but tempered that scholarship with shorter, simpler articles that were more intelligible to lay-readers. Thus, the 9th and 11th editions had 17,000 and 40,000 articles, respectively, although they were roughly equivalent in size. This shift accommodated the American business strategy of popularizing the Britannica for a mass market, while still retaining its quality as a reference work.

The 11th edition employed 35 named female contributors, out of 1500 total (2.3%). Although this was not much of an increase over the 10th edition (which named 37 female contributors out of 1800 total), it was heralded publicly as a major advance in recognizing the contributions of women in learned circles. However, the 11th edition did employ hundreds of women to write unsigned articles; some women, such as Irish medical expert Harriet Hennessy, even rose to be (uncredited) department editors.

, where they have remained ever since. In 1922, a 3-volume supplement to the 11th edition was released that summarized the developments just before, during and after World War I; these three volumes, taken together with the 11th edition, became known as the 12th edition. Horace Hooper died in 1922, a few weeks after the publication of the 12th edition. This edition was a commercial failure, losing Sears roughly $1.75 million dollars, after which Sears gave it back to Hooper's widow, Harriett Meeker Cox, and her brother, William J. Cox, who ran the company from 1923-1928.

The passage of a few years led to a better perspective on that era. In 1926, the Britannica released three new volumes covering the history of 1910-1926, which were intended to supplant those of the 12th edition.

 identified and fixed a key vulnerability of Britannica, namely, that its sales (and, hence, the company's income) fluctuated strongly over the life-cycle of an edition. After the release of a new edition, sales would generally begin strong, and decline gradually for 10–20 years as the edition began to show its age; finally, sales would drop off precipitously with the announcement that work had begun on a new edition, since few people would buy an obsolete encyclopedia that would soon be updated. These strong fluctuations in sales led to economic hardship for the Britannica.

To address this problem, Powell suggested in 1933 the policy of continuous revision, with the goal of keeping the Britannica "always timely and always salable". The basic idea was to maintain a continuous editorial staff that would constantly revise the articles on a fixed schedule. Earlier encyclopedias did not maintain a continuous editorial staff, but rather assembled one just prior to beginning a new edition. Rather than releasing supplemental editions or volumes, new printings would be made every year with only enough copies made to cover the sales for that year. An analysis of the Britannica's articles suggested that roughly 75% required only occasional revising, whereas 25% required revision every 1–3 years. The articles were therefore divided into 30 classifications and a schedule for their revision worked out, such that every article would be checked at least twice a decade.

Powell also conceived the Britannica's "Book of the Year", in which a single volume would be released every year covering the developments of the previous year, particularly in rapidly changing fields such as science, technology, culture and politics. The "Book of the Year" continues to be published even today. Powell also introduced the Library Research Service (1936), in which owners of the Britannica could write to have their personal questions researched and answered by the editorial staff.

Under Powell's leadership, the Britannica began to capitalize on its reputation by aggressively developing "spin-offs", such as the 12-volume Britannica Junior for children (published 1934, and revised to 15 volumes in 1947), the historical timeline The March of Man (published 1935, and edited by Albert Bushwell Hart, Isaac J. Cox and Lawrence H. Dawson), the Encyclopædia Britannica World Atlas (published 1942, and prepared by G. Donald Hudson) and Ten Eventful Years, a summary of the national and international events surrounding World War II (1937–1946).

 declined the offer, viewing the mission of the university as not entirely consistent with a large commercial publishing house; however it continues even today to be involved in its production, offering editorial advice and allowing its name to be associated with the Britannica. Thus, in 1943, the wealthy and powerful William Benton, a former U.S. senator and advertising executive, obtained exclusive control of the Britannica, which he published until his death in 1973.

First version (1974–1984)

Despite the policy of continuous revision, the 14th edition of the Britannica gradually became outdated, much as its predecessors, the 9th and 11th editions. Beginning in the early 1960s, the failings of the 14th edition began to be collated and published by physicist

, culminating in his highly critical 390-page book, The Myth of Britannica (1964). Goaded into action, the Britannica began to work on a new edition, the current 15th.

The 15th edition was produced over ten years at a cost of $32 million dollars and released in 1974 in 30 volumes. The so-called New Encyclopædia Britannica (or Britannica 3) had a unique three-part organization: a single Propædia (Primer for Education) volume, which aimed to provide an outline of all known, indeed knowable, information; a 10-volume Micropædia (Small Education) of 102,214 short articles (strictly less than 750 words); and a 19-volume Macropædia (Large Education) of 4,207 longer, scholarly articles with references, similar to those of the 9th and 11th editions. The Micropædia and Macropædia articles are listed in alphabetical order; the 4,287 contributors to the Macropædia articles are identified scrupulously, but the Micropædia articles are generally anonymous and unreferenced.

This 15th edition had no general index, which had been a feature of the Britannica since its 7th edition; even in the 2nd edition, individual long articles had their own indices. The idea of Mortimer J. Adler was that the Propædia and the Micropædia could serve the role of an index. More generally, Dr. Adler felt that the Britannica should not merely serve as a reference work, but also aspire to be a categorization of omne scibile (everything knowable), to fulfill Francis Bacon

's grand conception of epistemology. Thus, the Propædia was intended to be the road-map of all knowledge, within which every fact, technique, and theory could be organized.

The lack of an index and the unusual organization into two sets of alphabetically organized articles provoked much criticism. In a typical contemporary assessment, "It is called the Micropædia, for 'little knowledge,' and little knowledge is what it provides. It has proved to be grotesquely insufficient as an index, radically constricting the utility of the Macropædia." or, more laconically, "This arrangement has nothing to recommend it except commercial novelty". Most readers could not predict whether a given subject would be found in Micropædia or the Macropædia; the criteria by which the articles were sorted were not obvious even to scholars, despite Dr. Adler's claims that the sorting followed naturally from the Propædia's outline of all knowledge.

Second version (1985–present)

In 1985, the Britannica responded to reader requests by restoring the index as a two-volume set. The number of topics indexed by the Britannica has fluctuated from 500,000 (1985, the same as in 1954) to 400,000 (1989,1991) to 700,000 in the current 2007 print version. Presumably, this recent increase reflects the introduction of efficient electronic indexing, since the size of the encyclopedia has remained nearly constant at approximately 40 million words from 1954 to the present and far less than 40% of the encyclopedia has changed from 1985 to 2007.

 encyclopedia, but the offer was declined. Senior managers at Britannica were confident in their control of the market and that their healthy profits would continue. At this time complete sets of the encyclopedia were priced between $1,500 and $2,200, and the product was considered part of a luxury brand with an impeccable reputation handed down from generation to generation.

.

In 1990 the Britannica's sales reached an all-time high of $650 million, but Encarta, released in 1993, soon became a software staple with almost every computer purchase and the Britannica's market share plummeted. Britannica Inc. countered by offering a CD-ROM version of their product, although it could not generate the print version's $500–600 in sales commissions. Britannica Inc. decided to charge $995 for just the CD-ROM, while bundling a free disc with the print version, hoping that including the CD-ROM would persuade buyers to stay with the brand.

In 1994 an online version was launched, with subscriptions for sale for $2,000. By 1996 the price of the CD-ROM had dropped to $200, and sales had dropped to $325 million — about half of their 1990 levels. Only 55,000 hard copy versions were sold in 1994, compared with 117,000 in 1990, and sales later fell to 20,000. Facing financial pressure, Britannica Inc. was bought in 1996 by Swiss financier Jacob Safra

McHenry believes these failures were due to a reluctance among senior management to fully embrace the new technology, caused largely by the overriding influence of the sales staff and management. The sales personnel earned commissions from door-to-door selling of the print encyclopedias, which McHenry believes led to decisions about the distribution and pricing of the electronic products being driven by the desires of the sales personnel rather than market conditions and customer expectations.
