The one-volume '''Propædia''' is the first of three parts of the
''. The ''Propædia'' is intended as a topical organization of the ''Britannica's'' contents, complementary to the alphabetical organization of the other two parts. 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 Index as a two-volume set in 1985. The core of the ''Propædia'' is its 'Outline of Knowledge', which seeks to provide a logical framework for all human knowledge; however, the ''Propædia'' also has several appendices listing the staff members, advisors and contributors to all three parts of the ''Britannica''.
Analogous to the ''Britannica'' itself, the ''Outline'' has three types of goals:

, all the articles of the ''Britannica'' were commissioned based on the ''Outline of Knowledge''.
The ''Outline'' has ten Parts, each with an introductory essay. The authors of these essays are listed below in the final column of Table 1. The same ten men were responsible for developing the outline for their Part, in consultation and collaboration with a handful of other scholars; in all, 86 men and one woman were involved in developing the Outline of Knowledge (see Table 2 below).
Each of the Parts is divided into 2-7 Divisions, which are themselves divided into 2-11 Sections. These Sections form the basic categories of knowledge in the
, and each one is given a special three-part numerical code to encode its place in the ''Outline's'' hierarchy. For example, the section "Military Technology" has the code "736" indicating that it is the 6th Section of the 3rd Division ("Major Fields of Technology") of the 7th Part ("Technology"). Forward slashes are used when a Part, Division or Section has more than one digit; for example, the Section "History and Philosophy of Logic" has the code "10/11" indicating that it is the 1st section of the 1st Division ("Logic") of the 10th Part ("The Branches of Knowledge").
