The concept of social capital and its contribution to success and well-being in a variety of settings has potential for academic library outreach. Research has found that those with extensive and varied networks of social relationships can benefit in myriad ways, including academic and professional achievement. A connection has also been found between lower levels of social capital and negative effects on individuals as well as communities generally. Academic libraries are strategically positioned to enhance the social capital of their users, effecting positive differences in engagement, retention, and success after graduation.
