This paper reports on a series of panels and workshops held at the Bled eConference since 2004. It aims at reconstructing the developing understanding of Inter-organizational Information Systems (IOIS) over the years as evidenced by these workshops, which have been designed to provide a forum to discuss emerging topics, fields, and strategies for IOIS research on a network and industry level. This paper provides an overview of the workshops and a detailed coverage of the last one in order to give a thorough and vivid account of its contributions. The paper not only takes a historical lens in documenting the workshops but also in discussing the transformation from strategic systems to information infrastructures. It reflects the enabling role of the Bled eConference for workshops series and the workshops’ contribution to the Bled conference.
