IGB established the Distinguished Seminar Series in 1990 to encourage the exchange of ideas across the barriers of time, space and disciplines. Each year we invite distinguished professionals, to give presentations on topics of current interest. Speakers may discuss recently completed or early-stage research that they have undertaken or report other types of professional activity. Some topics align closely with our current research directions, while others represent areas of interest to the library and information science community that are not formally being studied by our researchers. Diversity of topics is essential to meeting the purpose of the Distinguished Seminar Series.
