    Abstract
    The large number and variety of online databases in the field of environment sciences and chemistry underlies the need for a cooperative evaluation approach. Presents 2 evaluation criteria, divided into 4 headings; general criteria (size of data source, cost of 1 hour searching, updating of database, availability on other media); chemical relevant criteria (number of chemicals, identification parameters of chemicals, test set chemicals, development of chemicals), environmental relevant criteria (information parameters for chemicals, parameter development); and criteria describing environmental chemicals (use of chemicals, quality of database). A 6 number scoring system is applied to these criteria and the Hasse diagram technique is presented for 19 bibliographic online databases using these criteria. Using this technique, 'good' and 'bad' databases are identified and changes in the database content from 1995 to 1998 can be visualized
