The fifth edition of a reference volume designed to identify researchers and describe current research on issues of concern to the independent sector is presented. Its purpose is to offer an avenue for sharing information and to assist researchers in contacting colleagues who have similar research interests but who may be working in widely varying situations. It includes information on research covering giving, voluntary action, and not-for-profit activities. Ten sections are as follows: (1) general reference; (2) economics and finance; (3) government issues; (4) volunteerism; (5) nonprofit management; (6) philanthropy; (7) international; (8) special industry and subject studies; (9) index of authors; and (10) index of project titles. It is noted that the last edition of"Research in Progress" referenced 657 projects, and this edition references 916 projects with 560 entirely new entries. The topical areas with the fastest growth since 1982 are voluntarism, philanthropy, international studies, and general studies. Areas in which progress has not been made include special industry studies, environmental studies, consumer protection, and civil rights and advocacy organizational studies. Research Summary Sheets are included at the back of the volume, and readers are encouraged to submit their research for inclusion in the next volume. (SM)
