Table 3 includes geographic location and affiliation information for PPsych and JAP. It is important to note that the total number of authors computed for a given period may be slightly different when this total is computed from different sources. Specifically, as noted in Table 3 regarding PPsych, the total number of authors for the period from 1983 to 1987 is 336 on the basis of adding the academic status based categories and 333 on the basis of adding the location based categories. These minor differences, which have no impact on our substantive results or conclusions, are due to a highly reliable, yet less than perfect, coding process as described above (i.e., high correlations between counts produced by independent coders).
