In an index, cross-references draw connections between topics – guiding readers from one heading to a related heading that will lead them to the information required or to additional information on the same subject.
Four expressions are often used to indicate cross-references. These are always in italics, but either in lower case or minimal capitals: see, see also, see under and see also under. Entries after the expression are presented as they appear in the index heading (ie the same capitalisation and whether roman or italic) and are separated by semicolons:
alien species see invasive species
bushfires, 262, 274, 317, 322–333
water quality impacts, 231, 854
see also fire frequency; fire regimes
turbidity see under water quality
net economic returns, 1, 20, 26–28, 500–501, 505–506
trends by fishery, 22–25
see also economic status under specific fisheries
