    Abstract
    Describes an approach to retrieving environmental sciences information on the Internet using metadatabases. an inf-sheet is created in a flat file system for each resource. The contents of theses sheets are structured by different fields which hold different types of information. 2 classes of information can be distinguished: information describing the content of a resource, which is searchable, and information which links to the resources (URL). A rough automated selection is performed, humans analyze the pre selected resources, and a final selection and indexing is carried out. An algorithm which controle the validity of the meta information is implemented. Describes 2 implemented examples, the Register of Ecological Models and the Metadatabase of Internet Resources
