The public library is uniquely situated to meet the information needs of older adults and can also assist them in both finding ways to make their lives meaningful and staying in the mainstream. This study involved a mail survey of the public libraries of Ohio regarding their services for adults aged 65 and over. One hundred and eighty-four libraries reported on extension services, special resources, group activities, special services, areas of institutional support, and utilization of older adults as employees and volunteers. The most frequently reported extension service is homebound services. Large print books are considered the most common special resources and lectures are the most common group activities. Information and referral is the most frequently reported special service. Most libraries cooperate with other community organizations. Older adult services received low priority in most libraries although many libraries employed older adults and utilized them as volunteers. Results of this study were similar to those reported by national surveys done in the past. Eleven tables provide data on adult services. The survey on adult services and cover letters are appended.
