Abstract
The following chapter will first deal with asynchronous and synchronous message and communication systems. Asynchronous communication may be used in situations where people have a shared task but they do not work simultaneously on it. There are no real-time requirements. Examples of these group-ware systems are information exchange, distance learning or bulletin boards. The architecture and functionality of a typical email system will be discussed. Further attention will be directed towards synchronous communication as exemplified by video conferences.
The second part of the chapter presents an information management approach to support the work on shared information in the context of workgroups. We will discuss an architecture for hypermedia systems, the hypertext abstract machine, and the Dexter reference model which facilitates the interoperability between different hypermedia systems. The navigation problem in large information spaces and hypertext-specific solutions are presented.
The IBIS method provides functions to systematically structure the problem solving information. Finally, we will present the information space of the Campiello system, a community support system for tourist applications.

The concept of concurrency in hyperdocuments was first mentioned in the context of Augment (Engelbart 1982). Several persons may work on the same hyper-document synchronously; the hyperdocument may be distributed among several computers.
