An information retrieval/distribution system configured on computers and for requesting the retrieval of information which is scattered on a network, comprises an information retrieval request unit for requesting the retrieval of information and a plurality of database management units for managing databases. Each of the plurality of database management units (e.g., each manager) has management information about the databases which are managed by each manager, and has management information about the databases which are managed by other database management units which can be connected to each manager through said network. When a retrieval criterion is input to the information retrieval request unit, one of the plurality of database management units (e.g., one manager), based on the management information in one manager, retrieves the information in the databases managed by one manager, and requests any other database management unit (e.g., other manager) managing the database in which the information related to said retrieval criterion is stored to retrieve the information in the databases managed by other manager, thereby distributing the information corresponding to the retrieval criterion to the information retrieval request source.
