Cirrus is a library search system. It combines different ways of searching: Directly by search input, selectively by lists in subject areas or by browsing through tag clouds. In the book sug-
gestion area the search results get visual and can be refined through adding new tags. For every book the user can get a preview with additional information. By logging in the sys-
tem he gets more options e.g survey or renew borrowed books.
The concept 'cirrus' was developed during my third semester interaction design course.
