Purpose - This study aims to examine library programming for active older ("third age") adults and give suggestions for future improvements. In addition to covering research specific to library programming for these adults, which is limited, this review will also survey the literature on lifelong learning for this population. Design/methodology/approach - This paper includes a literature review on library programming geared specifically to active, older adults and a survey of literature on lifelong learning for the "third agers". Findings - Demographics show that older adults are a growing population, not only in the USA, but worldwide. Many baby boomers have already entered or soon will be entering the "third age". Most libraries are not providing specific programming to support these older lifelong learners. In the USA, baby boomers have the highest net worth of any generation, and as such, are an important fundraising source. Research indicates that older adults participate in lifelong learning activities and will attend library programs of interest. Topics of interest include hobbies/leisure pursuits, humanities, social/international issues, religion/philosophy, arts, technology and nutrition/health/stress management. Practical implications - Libraries are missing a prime opportunity to expand services, develop library advocates and fundraise by ignoring the growing population of active older adults. Suggestions are given for how both public and academic libraries can take advantage of these opportunities. Social implications - Older adults are a rapidly growing population. Providing library programming for this group benefits both older adults and libraries. Originality/value - There are no known previous comprehensive literature reviews on library programming for older adults. Offering specific programming to this population has benefits for older adults, libraries and their communities.
