It is my great pleasure to welcome you to “Repositories in Cooperation”. Our panel for “Varieties of Cooperation” developed out of preparatory work for the Collaborative Research Center „Media of Cooperation“, in which we have attempted to refocus and reappropriate Susan Leigh Star’s and James Griesemer’s original notion of the boundary object. Within our 2015 workshop on “The Translation of Boundary Objects” we have started to re-engage with a more specific understanding that returns to Star’s list of four type of boundary objects: repositories, ideal types, coincident boundaries and forms/labels. The results of this have now been published in German as “Grenzobjekte und Medienforschung”, along with a translation of ten seminal texts by Star and her collaborators. As Erhard Schüttpelz has shown in his commentary on “This is Not a Boundary Object” all four types deal with the relation between modularity and extendability, with the relation between “parts” and “wholes”. 
I was just looking up some etymological details concerning “cooperation” and “coordination.” Google Ngram still is a rather intransparent source, but using it along with the Oxford English Dictionary gives a nice quantitative vs. qualitative account. This blogpost comes without interpretation, but with an embedded ngram. Consider it just being a trace of my work (or Google’s).
The Swiss Federal Archives have been publishing a video documentation of their „ICT@Admin“ conference. I had the privilege of being a part of this, so I include the video and abstract of my talk here. A complete documentation is also online, and the overall YouTube playlist is highly recommended.
CREDIT CARD MOBILITIES (Sebastian Gießmann, Siegen, March 26 2015)
The talk sketches out a praxeological history of the credit card, with an emphasis on its mediating qualities and operational status within bureaucratical frameworks. Temporal borrowing via credit card is regarded as a highly dynamic social technology that produces emergent topologies through distributed mobile payments. The formative years of the American credit card (1950-1975) are analyzed along with approaches from ethnomethodology (Harold Garfinkel) and actor network theory (Michel Callon). Cooperative media practices are key to understanding the relation between the administrative handling of „accounts“ and emerging social networks. This includes (1) Dining, traveling, and charging, (2) Accounting for trust and credit, (3) Mass mailing and advertising new ways of payment, (4) Building „co-opetitive“ platforms for networks and (5), the digital momentum of credit cards as immutable mobiles.
