Recently, many attempts are made to edit traditional coursebooks enriched by multimedia and to make them available via the Web. For the Multibook project, here are two objectives we are aiming at: to use the possibilities of computers to generate lessons with multimedia material and to be adaptive to the user's needs, such that different views of the topic can be generated and presented. The system produces lessons tailored to the specific user and hence allows for an optimal teaching.

The dynamic generation of lessons is a difficult problem requiring research in diverse areas:

• The system has to know about  the requirements of the individual learner, which can be realized by employing a user profile
• The flexible designing of lessons and also the change on-the-fly of lessons is possible by using a modular knowledge base
• The exchange of information resources via the Web becomes sensible by describing the resources by metadata
• To include the user actively into the process of learning, interactive simulations are integrated in Multibook.
• Knowledge Base Information has to be available in modular pieces, structuring the domain by formal representation of the content

	The Multibook knowledge base: Material has to be modular, for choosing topics an ontology is necessary.
	Learning Objects Standardized descriptions of the modules and more
	Animation and Simulation: Employing interactive media to make complex processes clear. The dynamic composition of these topics is a problem
	The user profile: How Multibook collects information about the learner.
	Adaptivity: Conducted self-service, bringing together the decisions of the user and the machine
	Architecture and Technique: Technical realization
