Data on interlibrary loan transactions occurring during July and August 1979 were analyzed to determine comparative turnaround and delivery times for 5 Quebec and 11 Ontario universities. The numbers of working days of positive responses for loans and photocopies and the numbers of positive and negative responses for combined loans and photocopies were calculated by subtracting the date that a request was made from the date when the request item or negative response was received. It was found that there is a considerable difference in turnaround times between Quebec and Ontario universities and for photocopies and loans; negative responses constituted 25.7 percent of the replies to requests made to Quebec universities and 27 percent of the requests to Ontario universities. Discussion of the findings includes suggestions for the improvement of interlibrary loan services, and four tables of data are appended. (RBF)
