From the moment in March 1879 whenMurray signed the contract with Oxford University Press to be the next Editorof the Dictionary, and he took possession of 2 tons of slips at his house, hisfamily was immediately part of the project (whether they liked it or not)sorting out the slips. Their house was a workplace and the family aworkforce.
Perhaps one of the first sources of counting slips in weight rather than number!
