Sheldon offers a succinct, simple discussion of social media through the lens of communication studies, connecting classic theories of interpersonal and mass communication to many of the social media technologies common to the modern media ecology. In each chapter she draws on established research in communication studies and related fields (e.g., media psychology) to illustrate the many uses and effects of social media. . . .Since few social media textbooks available today are accessible to nonspecialists, Sheldon's volume will be an excellent complementary resource for those in the classroom. Sheldon makes simple yet strong connections between social media technologies and the established body of communication studies poised to explain those technologies and their use by and effects on individuals and on society more broadly. Those looking for an orientation to social media from a communication studies perspective will find this a useful entry point. . . .Summing Up: Recommended. Lower-division undergraduates; general readers.
