The paper looks at the virtual organization in an electronic market environment and the different models of communication and management that may be required. The authors begin by providing some clear definitions of virtual cultures and different models of virtuality that can exist within the electronic market. Degrees of virtuality can be seriously constrained by the extent to which organizations have predefined communication linkages in the marketplace and the extent to which these can be substituted by virtual ones, but also by the intensity of virtual linkages which support the virtual model. Six virtual organizational models are proposed within a dynamic framework of change. In order to realize strategic advantage, virtual organizations must align their management models and communication processes with their virtual culture.

This paper describes a methodology for testing the usability of a digital library. The paper also presents the results from using this methodology on a specific library of technical manuals. The testing process involves timing subjects while they look up facts in comparable libraries of online and paper documents. They are timed for both how long they take to find a desired manual in the library and how long they take to find a desired fact in a chosen manual. Next, the subjects fill out a questionnaire on which type library they prefer using and why. The objective time results and the subjective preferences are compared and analyzed.
