Abstract
This paper describes the environment that supports selection of Z39.50 databases for users. The environment allows users to share information of Z39.50 databases in WWW. The present authors develop the WWW-Z39.50 client. In this environment, the users can share information which other users organize by themselves. When a user clicks one of list of Z39.50 databases, which is shared information, the window for retrieval of the database will be opened for the user to start his/her retrieval immediately.
