Matthew Leigh, From Polypragmon to Curiosus: Ancient Concepts of Curious and Meddlesome Behaviour
(Oxford: Oxford University Press, 2013), p. 2:
In order to answer the questions that I set myself it has been necessary to adopt the methods of the lexicographer. I have made no little use of the various electronic resources that have so accelerated the first stages of any word search, but am also in debt to the work of those less technologically privileged inquirers who issued the first concordances to individual authors or composed the meticulous entries to be found in Stephanus' Thesaurus Linguae Graecae and the Thesaurus Linguae Latinae. More often than not, however, I have found that to leap in and out of a text only where a particular word is to be found can lead to but a superficial understanding, and have therefore taken the time to read whole works through where it seemed important to do so.
