Editions

The Britannica has been issued in 15 editions, with multi-volume supplements to the 3rd and 5th editions (see the Table below). The 10th edition was only a supplement to the 9th, just as the 12th and 13th editions were supplements to the 11th. The 15th underwent massive re-organisation in 1985, but the updated, current version is still known as the 15th.

Throughout history, the Britannica has had two aims: to be an excellent reference book and to provide educational material. In 1974, the 15th edition adopted a third goal: to systematise all human knowledge. The history of the Britannica can be divided into five eras, punctuated by changes in management or re-organisation of the dictionary.

1768–1826

In the first era (1st–6th editions, 1768–1826), the Britannica was managed and published by its founders, Colin Macfarquhar

. Under Mortimer J. Adler (member of the Board of Editors of Encyclopædia Britannica since its inception in 1949, and its chair from 1974; director of editorial planning for the 15th edition of Britannica from 1965), the Britannica sought not only to be a good reference work and educational tool but to systematise all human knowledge. The absence of a separate index and the grouping of articles into parallel encyclopaedias (the Micro- and Macropædia) provoked a "firestorm of criticism" of the initial 15th edition.*

* In response, the 15th edition was completely re-organised and indexed for a re-release in 1985.

The official title of the 15th edition is the New Encyclopædia Britannica, although it has also been promoted as Britannica 3.

Criticisms

The Britannica has received criticism, especially as editions become outdated. It is expensive to produce a completely new edition of the Britannica, and its editors delay for as long as fiscally sensible (usually about 25 years). For example, despite continuous revision, the 14th edition had become outdated after 35 years (1929–1964). When American physicist Harvey Einbinder

 detailed its failings in his 1964 book, The Myth of the Britannica, the encyclopaedia was provoked to produce the 15th edition, which required 10 years of work. It is still difficult to keep the Britannica current; one recent critic writes, "it is not difficult to find articles that are out-of-date or in need of revision", noting that the longer Macropædia articles are more likely to be outdated than the shorter Micropædia articles. Information in the Micropædia is sometimes inconsistent with the corresponding Macropædia article(s), mainly because of the failure to update one or the other. The bibliographies of the Macropædia articles have been criticised for being more out-of-date than the articles themselves.

Editorial choices

The
Britannica is occasionally criticised for its editorial choices. Given its roughly constant size, the encyclopaedia has needed to reduce or eliminate some topics to accommodate others, resulting in controversial decisions. The initial 15th edition (1974–1985) was faulted for having reduced or eliminated coverage of children's literature
Children's literature

, and a two-volume index. The Britannicas articles are found in the Micro- and Macropædia, which encompass 12 and 17 volumes, respectively, each volume having roughly one thousand pages. The 2007 Macropædia has 699 in-depth articles, ranging in length from 2 to 310 pages and having references and named contributors. In contrast, the 2007 Micropædia has roughly 65,000 articles, the vast majority (about 97%) of which contain fewer than 750 words, no references, and no named contributors. The Micropædia articles are intended for quick fact-checking and to help in finding more thorough information in the Macropædia. The Macropædia articles are meant both as authoritative, well-written articles on their subjects and as storehouses of information not covered elsewhere. The longest article (310 pages) is on the United States, and resulted from the merger of the articles on the individual states

.

Information can be found in the Britannica by following the cross-references in the Micropædia and Macropædia; however, these are sparse, averaging one cross-reference per page. Hence, readers are recommended to consult instead the alphabetical index or the Propædia, which organises the Britannicas contents by topic.

The core of the
Propædia is its "Outline of Knowledge", which aims to provide a logical framework for all human knowledge. Accordingly, the Outline is consulted by the Britannicas editors to decide which articles should be included in the Micro- and Macropædia. The Outline is also intended to be a study guide, to put subjects in their proper perspective, and to suggest a series of Britannica articles for the student wishing to learn a topic in depth. However, libraries have found that it is scarcely used, and reviewers have recommended that it be dropped from the encyclopedia. The Propædia also has color transparencies of human anatomy and several appendices listing the staff members, advisors, and contributors to all three parts of the Britannica.

Taken together, the Micropædia and Macropædia comprise roughly 40 million words and 24,000 images. The two-volume index has 2,350 pages, listing the 228,274 topics covered in the Britannica, together with 474,675 subentries under those topics. The Britannica generally prefers British spelling

; for example, it uses colour (not color), centre (not center), and encyclopaedia (not encyclopedia). However, there are exceptions to this rule, such as defense rather than defence. Common alternative spellings are provided with cross-references such as "Color: see Colour."

Since 1936, the articles of the Britannica have been revised on a regular schedule, with at least 10% of them considered for revision each year. According to one Britannica website, 46% of its articles were revised over the past three years; however, according to another Britannica web-site, only 35% of the articles were revised.

The alphabetisation of articles in the Micropædia and Macropædia follows strict rules. Diacritical marks
Diacritic

 – and letter grades of A–D or F were awarded in four categories: coverage, accuracy, clarity, and recency. In all four categories and for all three encyclopaedias, the four average grades fell between B− and B+, chiefly because none of the encyclopaedias had an article on sexual harassment in 1994. In the accuracy category, the Britannica received one "D" and seven "A"s, Encyclopedia Americana received eight "A"s, and Collier's received one "D" and seven "A"s; thus, Britannica received an average score of 92% for accuracy to Americana′s 95% and Collier's 92%. The 1994 Britannica was faulted for publishing an inflammatory story about Charles Drew that had long been discredited. In the timeliness category, Britannica averaged an 86% to Americana′s 90% and Collier's 85%. After a more thorough qualitative comparison of all three encyclopedias, Kister recommended Collier's Encyclopedia as the superior encyclopaedia, primarily on the strength of its excellent writing, balanced presentation and easy navigation.

Collier's has not been in print since 1998. The Encyclopedia Americana was last published in 2006. Britannica was last published in 2010.

articles are the work of the editorial staff and identified outside consultants. Thus, a Britannica article either has known authorship or a set of possible authors (the editorial staff). With the exception of the editorial staff, most of the Britannicas contributors are experts in their field—some are Nobel laureates. By contrast, the articles of Wikipedia are written by a community of editors with varying levels of expertise: most editors do not claim any particular expertise; of those who do, many are anonymous
Anonymity

 and have no verifiable credentials. Another difference is the pace of article change: the
Britannica is published in print every few years, while Wikipedia's articles are likely to update frequently. Robert McHenry stated that Wikipedia cannot hope to rival the Britannica in accuracy.

On 14 December 2005, in a study, the journal
Nature chose articles from both sites in a wide range of topics and sent them to what it called "relevant" field experts for peer review. The experts then compared the competing articles—one from each site on a given topic—side by side, but were not told which article came from which site. Nature got back 42 usable reviews from its field of experts.

In the end, the journal found just eight serious errors, such as general misunderstandings of vital concepts, in the articles. Of those, four came from each site. They did, however, discover a series of factual errors, omissions or misleading statements. All told, Wikipedia had 162 such problems, while Britannica had 123.

That averages out to 2.92 mistakes per article for Britannica and 3.86 for Wikipedia. In its detailed 20-page rebuttal, Encyclopædia Britannica, Inc. characterized Natures study as flawed and misleading and called for a "prompt" retraction. It noted that two of the articles in the study were taken from a Britannica year book, and not the encyclopedia; another two were from Compton's Encyclopedia (called the Britannica Student Encyclopedia on the company's web site). The rebuttal went on to mention that some of the articles presented to reviewers were combinations of several articles, and that other articles were merely excerpts but were penalised for factual omissions. The company also noted that several facts classified as errors by Nature were minor spelling variations, and that several of its alleged errors were matters of interpretation. Nature defended its story and declined to retract, stating that, as it was comparing Wikipedia with the web version of Britannica, it used whatever relevant material was available on Britannica's website.

5 Vols. 30–32 ... the New volumes constituting, in combination with the twenty-nine volumes of the eleventh edition, the twelfth edition

6 This supplement replaced the previous supplement: The three new supplementary volumes constituting, with the volumes of the latest standard edition, the thirteenth edition.

7 This edition was the first to be kept up to date by continual (usually annual) revision.

8 The 15th edition (introduced as "Britannica 3") was published in three parts: a 10-volume Micropædia (which contained short articles and served as an index), a 19-volume Macropædia, plus the Propædia (see text). It was reorganised in 1985 to have 12 and 17 volumes in the Micro- and Macropædia.

9 In 1985, the system was modified by adding a separate two-volume index; the Macropædia articles were further consolidated into fewer, larger ones (for example, the previously separate articles about the 50 U.S. states were all included into the "United States of America" article), with some medium-length articles moved to the Micropædia.

The first CD-ROM edition was issued in 1994. At that time also an online version was offered for paid subscription. In 1999 this was offered for free, and no revised print versions appeared. The experiment was ended in 2001 and a new printed set was issued in 2001.
