The volumes of this classic series, now referred to simply as Zechmeister after its founder, L. Zechmeister, have appeared under the Springer Imprint ever since the series' inauguration in 1938. The volumes contain contributions in various topics related to the origin, distribution, chemistry, synthesis, biochemistry, function or use of various classes of naturally occurring substances ranging from small molecules to biopolymers. Each contribution is written by a recognized authority in his field and provides a comprehensive and up-to-date review of the topic in question. Addressed to biologists, technologists, and chemists alike, the series can be used by the expert as a source of information and literature citations and by the non-expert as a means of orientation in a rapidly developing discipline.

When this classic volume first appeared, academic freedom was a crucially important issue. It is equally so today. Hofstadter approaches the topic historically, showing how events from various historical epochs expose the degree of freedom in academic institutions. The volume exemplifies Richard Hofstader's qualities as a historian as well as his characteristic narrative ability.

Hofstadter first describes the medieval university and how its political independence evolved from its status as a corporate body, establishing a precedent for intellectual freedom that has been a measuring rod ever since. He shows how all intellectual discourse became polarized with the onset of the Reformation. The gradual spread of the Moderate Enlightenment in the colonies led to a major advance for intellectual freedom. But with the beginning of the nineteenth century the rise of denominationalism in both new and established colleges reversed the progress, and the secularization of learning became engulfed by a tidal wave of intensifying piety.

Roger L. Geiger's extensive new introduction evaluates Hofstadter's career as a historian and political theorist, his interest in academic freedom, and the continuing significance of Academic Freedom in the Age of the College. While most works about higher education treat the subject only as an agent of social economic mobility, Academic Freedom in the Age of the College is an enduring counterweight to such histories as it examines a more pressing issue: the fact that colleges and universities, at their best, should foster ideas at the frontiers of knowledge and understanding. This classic text will be invaluable to educators, university administrators, sociologist, and historians.
