indexes: simple entry

A simple entry is composed of an identifier (which is the heading) and a locator—the page or section number(s) where reference to the item may be found. The full heading is followed by a comma.

• Domino theory, 911
• Drainage basins, 4–6

Inversion in listings under keywords

Each item is listed according to the keyword, so inversion of phrases is often necessary: for example, control of drugs would be listed as Drugs, control of. The keyword should be the one that the reader is likely to look up in order to find the information required.

Put a comma between the two elements of the inverted phrase, as well as a comma at the end of the heading.

• Drugs, control of, 180–2
• Duties, customs and excise, 802, 812, 818, 824

Page numbers

The page numbers are given without p. or pp.

Inclusive numbers should be presented in accordance with the rules for inclusive numbers, e.g. 47–48, 10–16, 213–18, 1653–1703. Avoid the use of f., ff. and et seq. in place of numerals.
