This volume by the co-ordinator of the Electronic Teaching Centre for the Harvard College Libraries, begins with the premise that the impact of computers since the mid-1960s has been more profound than much of the library community has acknowledged. LaGuardia calls for a new way of looking at libraries that involves rethinking the most basic library structures and icons, reinventing an instruction vocabulary, and trying to anticipate the change and development of the role of libraries in the future.
