Data, states, events, information, experience and knowledge are present in all production enterprises in a vast array of forms. There is a common trend for storage, administration and processing of these in a distributed and connected information system for collaborative computer work. Work objects and data in a shared computer application can be continually changed and modified by different users working simultaneously with this application. Due to the different versions and the history of a common working object it becomes more and more important to be aware of the various states of the object. Within a recently completed comparative investigation study at the 'Laboratory for Human-Machine-Interaction' of the ifab-Institute, different ways of visualizing object versions and archives were evaluated. The investigation was based on different structured visualization forms.
