This study of four public libraries in Northeastern Ohio was conducted to determine the amount, if any, of restriction of access of materials to minors. Four libraries were opportunistically selected, and the director and children's librarian in each were interviewed. The emerging hypothesis was that some restriction would occur. The written policies and procedures of each library were examined to determine if they were practiced in reality. The study determined that there is a trend toward restriction of audiovisual material, especially video cassette tapes, to those under 18. Other less obvious restrictions on print material are also covered in this study. Through reading the literature on this topic, it was determined that these libraries are not unusual in their practice of restricting video tapes to adults only. The interview schedules are appended.
