  This paper presents an analysis of the user behavior of two different
domain-specific repositories. The web analytic tool etracker was used to gain a
first overall insight into the user behavior of these repositories. Moreover,
we extended our work to describe an apache web log analysis approach which
focuses on the identification of the user behavior. Therefore the user traffic
within our systems is visualized using chord diagrams. We could find that
recommendations are used frequently and users do rarely combine searching with
faceting or filtering.
