Searching for literature

Looking for a particular book, periodical or periodical article or for general literature on your subject?

We will show you how best to proceed, what search options our bonnus search portal gives you and how else you can run searches.

The bonnus search portal

Our search portal lets you find books, periodicals and articles in printed and electronic format. Besides the holdings of the University of Bonn’s libraries (Main Library, MNL Branch Library, faculty libraries), bonnus also provides additional bibliographical references such as full texts from databases and other external sources.

Getting your search started could not be easier using the search field on our homepage.

We also have a series of videos (with english subtitles) explaining how you can get the most out of the bonnus search portal.
