A progress report on the Center for the Study of Higher Education (CASE) National Donor Data Base Project is presented. The project, which began in June 1987, has proceeded in several phases: (1) data base design; (2) acquisition of data from participating institutions; (3) development of software to load each institution's data into the donor data base; (4) development of a questionnaire to capture data items not available in the data files; and (5) production of preliminary results from the aggregate of all institutions in the file. The CASE Donor Data Base is valuable for many useful research studies because: it is the only extant source of donor data with a nationwide scope; data are available for all large donors at many institutions; a study of the giving behavior of donors/alumni in the institution's home state can be compared with that of similar individuals residing in surrounding states or states more remote than surrounding ones; and it is possible to compare the magnitude of giving for individuals receiving the bachelor's degree with those receiving professional or other advanced degrees. Seven appendices provide information on: variables in institutional files; software vendors sending materials in response to the letter of inquiry; institutions expressing an interest in CASE donor data base project but not participating; on missing data percentages for key variables, institutions A-E; percentage of records containing valid values for combinations of variables; and data base preliminary results. The survey form itself is also appended. (SM)
