Editing IUCN Red List (section)

=== 1966–1977 Red Data Lists ===
Initially the Red Data Lists were designed for specialists and were issued in a loose-leaf format that could be easily changed.

The first two volumes of Red Lists were published in 1966 by conservationist Noel Simon, one for mammals and one for birds.<ref>{{Cite book |last=Simon |first=Noel |title=Red Data Book. Volume 1.
