The Encyclopædia Britannica is a general knowledge English-language encyclopaedia. It was published by Encyclopædia Britannica, Inc. and other publishers. It was written by more than 4,000 contributors; the 2010 version of the 15th edition, which spans 32 volumes and 32,640 pages, was the last printed edition. The Britannica is the English-language encyclopaedia, in print for the longest time: it lasted 244 years, it was first published between 1768 and 1771 as three volumes. The encyclopaedia grew in size: the second edition was 10 volumes, by its fourth edition it had expanded to 20 volumes, its rising stature as a scholarly work helped recruit eminent contributors, the 9th and 11th editions are landmark encyclopaedias for scholarship and literary style. Beginning with the 11th edition and following its acquisition by an American firm, the Britannica shortened and simplified articles to broaden its appeal to the North American market. In 1933, the Britannica became the first encyclopaedia to adopt "continuous revision", in which the encyclopaedia is continually reprinted, with every article updated on a schedule.

In March 2012, Encyclopædia Britannica, Inc. announced it would no longer publish printed editions, would focus instead on Encyclopædia Britannica Online. The 15th edition had a three-part structure: a 12-volume Micropædia of short articles, a 17-volume Macropædia of long articles, a single Propædia volume to give a hierarchical outline of knowledge; the Micropædia was meant as a guide to the Macropædia. Over 70 years, the size of the Britannica has remained steady, with about 40 million words on half a million topics. Though published in the United States since 1901, the Britannica has for the most part maintained British English spelling. Since 1985, the Britannica has had four parts: the Micropædia, the Macropædia, the Propædia, a two-volume index; the Britannica's articles are found in the Micro- and Macropædia, which encompass 12 and 17 volumes each volume having 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 65,000 articles, the vast majority of which contain fewer than 750 words, no references, 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 is on the United States, resulted from the merger of the articles on the individual states. A 2013 "Global Edition" of Britannica contained forty thousand articles. Information can be found in the Britannica by following the cross-references in the Micropædia and Macropædia. Hence, readers are recommended to consult instead the alphabetical index or the Propædia, which organizes the Britannica's 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 Britannica's editors to decide which articles should be included in the Micro- and Macropædia.

The Outline is intended to be a study guide, to put subjects in their proper perspective, 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, reviewers have recommended that it be dropped from the encyclopaedia; the Propædia has color transparencies of human anatomy and several appendices listing the staff members and contributors to all three parts of the Britannica. Taken together, the Micropædia and Macropædia comprise 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 prefers British spelling over American. However, there are exceptions 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. The alphabetization of articles in the Micropædia and Macropædia follows strict rules. Diacritical marks and non-English letters are ignored, while numerical entries such as "1812, War of" are alphabetized as if the number had been written out. Articles with identical names are ordered first by persons by places by things. Rulers with identical names are organized first alphabetically by country and by chronology. (That is, they are alphabetized as if their titles were "Charles, France, 3" and "Charles, Great Britain and Ireland

The 1978–79 NBA season was the 33rd season of the National Basketball Association. The season ended with the Seattle SuperSonics winning the NBA Championship, beating the Washington Bullets 4 games to 1 in the NBA Finals, a rematch of the previous year's Finals, but with the opposite result; the Buffalo Braves moved from Buffalo, New York to San Diego and became the San Diego Clippers, shifting from the Atlantic Division of the Eastern Conference to the Pacific Division of the Western Conference. The Detroit Pistons changed conferences, moving from the Midwest Division of the Western Conference to the Central Division of the Eastern Conference, where they remain today; the Washington Bullets shifted from the Central Division to the Atlantic Division. The franchise won its last division title until the 2016-17 season; the NBA adopted a three-official system similar to the one used in college basketball on a one-year trial basis. The experiment is scrapped for the 1979–80 season, but returns permanently in 1988–89.

The 1979 NBA All-Star Game was played at the Pontiac Silverdome in Pontiac, with the West defeating the East 134–129 in overtime. David Thompson of the Denver Nuggets won the game's MVP award; the Jazz played their final season in New Orleans, before moving to Salt Lake City. It would be 23 years; the Los Angeles Lakers play their final season under the ownership of Jack Kent Cooke. This was the last time both conference finals went to a deciding Game 7 until 2018.
