Secu- rity will be enforced to ensure that the data are not used for The list is divided into three parts: - Methods, Properties non-scientific purposes. and Applications - Compounds - Attributes. The Attributes list must be used in conjunction with the other two lists and defines One of the main uses is to find specialists on given topics. additional keywords for a better description of entries in those This means that it will be possible to search the database by lists. keywords and these must be defined in advance. The present list has been established on the basis of the keywords used I hope that everybody will find appropriate definitions in in the eighth edition of the Worm Directory. Some additional the present lists. For maximum efficiency of the search process keywords corresponding to new fields have been added.

This is one of the key points for the success of this there are about 1500 keywords. database. Methods, Properties and Applications This list contains the keywords for methods of study, properties (physical, chemical, biological.... ) and applications. It may be used with words defined in the Attributes list.
