Brittanica? Sheer luxury! When I were a lad, before I stopped bothering with homework altogether, I used my mother's old sets of encyclopedia from the 1950's. There was one 8-volume set of world encyclopedia, and a 3-volume encyclopedia of Australia. Sri Lanka was called Ceylon, the sun never set on the Empire/Commonwealth, there was this awfully interesting new social system in South Africa, and the Australian Aborigine, for utterly mysterious reasons, was a dying race (all very sad, but what can one do?). You'd have thought my teachers would have asked questions about my sources, but the late 70s/early 80s in #AU were very much like the 1950s elsewhere, only with worse fashion.
