In 1979, Edward P. Alexander's Museums in Motion was hailed as a much-needed addition to the museum literature. In combining the history of museums since the eighteenth century with a detailed examination of the function of museums and museum workers in modern society, it served as an essential resource for those seeking to enter to the museum profession and for established professionals looking for an expanded understanding of their own discipline. Now, Mary Alexander has produced a newly revised edition of the classic text, bringing it the twenty-first century with coverage of emerging trends, resources, and challenges.
