Richard E. Rubin’s book has served as the authoritative introductory text for generations of library and information science practitioners, with each new edition taking in its stride the myriad societal, technological, political, and economic changes affecting our users and institutions and transforming our discipline. Rubin teams up with his daughter, Rachel G. Rubin, a rising star in the library field in her own right, for the fifth edition. Spanning all types of libraries, from public to academic, school, and special, it illuminates the major facets of LIS for students as well as current professionals. Continuing its tradition of excellence, this text addresses the history and mission of libraries from past to present, including the history of service to African Americans; critical contemporary social issues such as services to marginalized communities, tribal libraries, and immigrants; the rise of e-government and the crucial role of political advocacy; digital devices, social networking, digital publishing, e-books, virtual reality, and other technology; forces shaping the future of libraries, including Future Ready libraries, and sustainability as a core value of librarianship; the values and ethics of the profession, with new coverage of civic engagement, combatting fake news, the importance of social justice, and the role of critical librarianship; knowledge infrastructure and organization, including Resource Description and Access (RDA), linked data, and the Library Research Model; the significance of the digital divide and policy issues related to broadband access and net neutrality; intellectual freedom, legal issues, and copyright-related topics; contemporary issues in LIS education such as the ongoing tensions between information science and library science; and the changing character of collections and services including the role of digital libraries, preservation, and the digital humanities. In its newest edition, Foundations of Library and Information Science remains the field’s essential resource.
