This book opens in Papeete one evening in 1935. Two American film-makers are in Tahiti to take location shots for Mutiny on the Bounty, and director Frank Lloyd laments his failure to find Captain Bligh’s log books. A small white-haired person of indeterminate appearance at the next table leans over: ‘I know where they are,’ she says. Of course she did. The logbooks were in the Mitchell Library, Sydney, and the speaker was Ida Leeson, Mitchell Librarian from 1932 to 1946. The Mitchell Library, located in the Public (now State) Library of New South Wales, is based on the priceless collection of Australiana and south-west Pacific materials donated in 1907 by the reclusive bibliophile David Scott Mitchell. Leeson, its second chief custodian, not only knew the vast collection backwards but added significantly to it. She also used it herself, a key to effective librarianship.
