The Design of Information Systems in the Social Sciences (DISISS) is a research project with the objective of carrying out research necessary for the effective design of information systems in the social sciences, whether by the creation of new systems or the modification of existing systems. This working paper reports the work to date on the collection and analysis of citations taken from social sciences journals. The data will be used in part to describe the major parameters of the social science literature, and in part for the work on clustering. The purpose of this report is four-fold. First, the general problem of selecting source journals will be considered. Second, the procedure adopted for the DISISS pilot citation study carried out in 1971 will be reviewed, together with a report of the study and an analysis of the findings. Third, the planning for the main DISISS citation study will be considered in the light of the pilot study, and fourth, progress on the main study will be reported.
