There are four library systems in Utah which provide bookmobile library service; the Salt Lake County Library, Salt Lake City Library, San Juan County Library and Utah State Library Commission. This study is limited to bookmobile library service in Utah and to librarians who first began library service. The history of bookmobiles in Utah began in 1947 when Ruth Vine Tyler suggested the need for this type of library service to the Salt Lake County Library Board. The Board purchased the first bookmobile and it began serving the public in 1949. The second library to put bookmobiles into service was the Utah State Library Commission which purchased its first bookmobile in 1958. San Juan County was the third library to purchase a bookmobile in 1959. The Salt Lake City Library began bookmobile service in 1960. Today there are nineteen bookmobiles serving nineteen of the twenty-nine Utah counties. (Author/NH)
