The production of the concordance was quite an epic task. It took all of the resources of the University of Toronto Computing Services, where the mainframe computer was reserved for the purpose for one night. The data was stored on the mainframe and the concordance programme commands were sent from a remote work station connected to the mainframe by a telephone connection. The output was put on 30 tapes, which were then taken to an outside company in North York where the concordance data was transferred to microfiches, which were subsequently published by a Toronto publishing company.
