Unbound by Place or Time: Museums and Online Learning by William B. Crow and Herminia Din examines how online learning environments provide a powerful set of new tools for museum educators to vastly expand the museum's audience and create new ways of interacting with visitors online and on-site. Providing practical advice and case studies while advocating a learner-centric, participatory model of education, the book challenges museums to re-examine their roles as 21st-century educational institutions.
