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difficult to keep the Britannica current ; one recent critic writes, " it is not difficult to find articles that are out-of-date or in need of revision ", noting that the longer Macropædia articles are more likely to be outdated than the shorter Micropædia articles.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 initial volume with the green spine is the Propædia ; the red-spined and black-spined volumes are the Micropædia and the Macropædia, respectively.

The one-volume Propædia is the first of three parts of the 15th edition of Encyclopædia Britannica, the other two being the 12-volume Micropædia and the 17-volume Macropædia.

A complementary study of the Micropædia found that geography accounted for 25 % of articles, science 18 %, social sciences 17 %, biography 17 %, and all other humanities 25 %.

The Micropædia articles are intended for quick fact-checking and to help in finding more thorough information in the Macropædia.

The Propædia also lists just under 4, 000 advisors who were consulted for the unsigned Micropædia articles.

Finally, the Propædia serves as an expanded Table of Contents for the Micropædia and Macropædia ; according to its designer, Mortimer J. Adler, all the articles of the Britannica were commissioned based on the Outline of Knowledge.

The 15th edition has a three-part structure: a 10-volume Micropædia of short articles ( generally fewer than 750 words ), a 19-volume Macropædia of long articles ( two to 310 pages ) and a single Propædia volume to give a hierarchical outline of knowledge.

In the fourth era ( 1974 – 94 ), the Britannica introduced its 15th edition, which was re-organised into three parts: the Micropædia, the Macropædia, and the Propædia.

Its elimination of the index was condemned, as was the apparently arbitrary division of articles into the Micropædia and Macropædia.

Since 1985, the Britannica has had four parts: the Micropædia, the Macropædia, the Propædia, and a two-volume index.

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.

Taken together, the Micropædia and Macropædia comprise roughly 40 million words and 24, 000 images.

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

The editorial staff help to write the articles of the Micropædia and some sections of the Macropædia.

Encyclopædia Britannica, Inc. now owns registered trademarks on the words Britannica, Encyclopædia Britannica, Macropædia, Micropædia, and Propædia, as well as on its thistle logo.

The 699 Macropædia articles are generally written by identified contributors, and the roughly 65, 000 Micropædia articles are the work of the editorial staff and identified outside consultants.

Introduced in 1974 with the 15th edition, the Propædia and Micropædia were intended to replace the Index of the 14th edition ; however, after widespread criticism, the Britannica restored the Index as a two-volume set in 1985.

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.

He has contributed 15 Micropædia articles, generally on religious organizations or movements: Aum Shinrikyo, Branch Davidian, Christian Science, Church Universal, Eckankar, Evangelical Church, The Family, Hare Krishna, Heaven's Gate, Jehovah's Witnesses, New Age Movement, Pentecostalism, People's Temple, Scientology and Wicca.
