Local genealogical societies and libraries have a common interest in providing genealogical researchers with materials and expert assistance. Societies and libraries can cooperate to meet genealogists' needs in several ways: (1) collection development, access, and creation; (2) indirect reference service (societies as a referral resource; (3) direct reference service to patrons (by mail and in person); and (4) programming, including the sharing of facilities for meetings and programs. Local genealogical societies (n=113) were surveys to identify characteristics of local genealogical societies and the extent of their own collections, to determine the degree to which they cooperate with libraries in their research area, and to assess the attitudes of societies toward libraries and their role in the genealogy network. The Local Genealogical Society Questionnaire with raw survey results and mailing enclosures and a list of local genealogical organizations in Ohio are appended. (53 references) (Author/DB)
