  We propose an online access panel to support the evaluation process of
Interactive Information Retrieval (IIR) systems - called IIRpanel. By
maintaining an online access panel with users of IIR systems we assume that the
recurring effort to recruit participants for web-based as well as for lab
studies can be minimized. We target on using the online access panel not only
for our own development processes but to open it for other interested
researchers in the field of IIR. In this paper we present the concept of
IIRpanel as well as first implementation details.
