The random selection of words by volunteers often resulted in themchoosing the same words with similar dates, and produced gaps in thequotation paragraphs, which Murray and his assistants had to fill by their ownmanual searching. This must have been like trying to find a needle in ahaystack. It was remarkable how successful Murray’s small team was at fillingthose gaps and finding earliest or latest quotations. Murray told thePhilological Society that this manual trawling for words had to be done forthe majority of words: ‘For more than five-sixths of the words we have tosearch out and find additional quotations in order to complete their historyand illustrate the senses; for every word we have to make a general search todiscover whether any earlier or later quotations, or quotations in other senses,exist.’
