A study was undertaken to determine what type of curriculum leadership roles school librarians were exerting in the nation's nineteenth largest school district, the Clark County Public Schools of Nevada. A 15-item questionnaire was mailed to 75 Clark County School District librarians; responses were received from 59 libraries (79%). Following a review of related readings on the subject of the school librarian as a school curriculum leader, analyses of the responses to each of the 15 questions included in the questionnaire are presented. Based on the analysis of the survey results and on the relationship of these analyses to the related readings and research cited, nine major conclusions are presented. They include: (1) school librarians do not see themselves as curriculum leaders; (2) school librarians are the media specialists of their schools; (3) school librarians are support, auxiliary personnel for classroom content area teachers; (4) school librarians are directly involved with reading programs at all grade levels; and (5) perceptions of the roles of school librarians are affected by the tone set by school principals for their respective schools. A series of tables divided by grade levels indicates the librarians' responses to the questionnaire. A 36-item bibliography is included. (THC)
