2) one may select a particular division of a part and examine the part of that division

3) one may focus on a single section or several sections of such a division and examine the contents of that section or those sections. The sectional outlines present, in orderly arrangement of topics, subjects that are treated in articles in Macropaedia and Micropaedia. The index, with its alphabetically arranged subjects headings, is indispensable in finding where a given subject appears in the Outline of Knowledge. These headings, where appropriate, carry specific citations pointing to the part, division, or section of the Propaedia that covers the subject in question. A subject referred to in a sectional outline is treated fully in an article of the same title being included in the list of suggested reading at the end of the section.

the headnotes are affixed to parts and divisions. Each of the 10 parts, 41 divisions, and 177 sections that make up the Propaedia is marked in the table of contents by a heading, which is followed by the number of the page on which that unit of the Propaedia begins. This structure provides three ways to utilize the outline: 1) one may turn on any of the parts as a whole and examine the contents of that part

the introductory essays for each of the ten parts illuminate the major concerns of that part of human knowledge

Propaedia or the Outline of Knowledge serves as the topical guide to the contents of the Encyclopaedia Brittanica in carrying out an orderly reading in any field of knowledge or learning chosen for in-depth study. Contains table of contents for an overview of the outline of knowledge as a whole
