Abstract	A study was made to compare early respondents with late respondents and with non-respondents, using data collected from a study of 1,186 adult borrowers of two public libraries. Usable information was collected from 718 respondents either by one or more telephone calls or by a postcard sent first or when there was no answer by telephone. The collected data were used to determine whether the differences between the first and second waves of respondents would have predicted correctly the known distribution of the non-respondents. Results of the study showed that the direction of change between the first and second waves does not usually predict correctly even the direction of difference between the second wave and the non-respondents, and the differences between the predicted and observed distributions of the non-respondents are often significantly greater than what would be expected by chance alone. Differences between early and late respondents cannot be relied on to predict correctly the nature of the non-respondents. (DB)
