We could use the techniques, well established, which have provided dictionaries of excellence, such as the Oxford English Dictionary. The painstaking scrutiny of texts from a range of contexts, the recording of new words and senses on slips, and the systematic correlation of these as a preliminary to representing patterns of usage: such steps are routine for major surveys of general vocabulary and could as readily be applied for a specialized vocabulary, such as the present undertaking. Needless to say, it would be a massive task – and one which, for linguistics and phonetics, has frequently been initiated, though without much progress. I am aware of several attempts to work along these lines, in Canada, Great Britain, Japan and the United States, sometimes by individuals, sometimes by committees. All seem to have foundered, presumably for a mixture of organizational and financial reasons.
