With social media a normal part of the daily lives of young adults, librarians are using these sites to promote library services. This article investigates the perceptions and attitudes of librarians toward social media as a tool for libraries and explores the way librarians utilize social media to portray professional roles and responsibilities to young patrons. This author focuses on the pastoral role of librarians and discusses possibilities for performing this role through social media. Although presently under-researched, social media provides librarians with one more avenue to advocate for, engage with, and support young adults.
