a view provider unit for creating, in response to a request from a user, view information in which electronic documents for which an access right is given to the user is indicated classified based on the type of access right referring to the access right database and for providing the view information to the user.

6. A document view providing device according to claim 5, wherein

the view provider unit creates view information indicating a folder structure in which electronic documents corresponding to a type of access right given to the requesting user are placed in a folder for each corresponding type of access right.

7. A document view providing device according to claim 6, wherein

a plurality of types of access right exist for each of a plurality of viewpoints, and

the view provider unit places a group of folders for types of access rights regarding the same viewpoint in one hierarchical level, creates a hierarchical folder structure having a tree form in which the hierarchical levels of the viewpoints are placed according to a predetermined order defined among the plurality of viewpoints, and creates a folder structure in which electronic documents are placed in the deepest folder in the folder structure, the electronic documents satisfying all types of access right corresponding to the folder and all ancestor folders.

8. A document view providing device according to claim 5, further comprising a property information collector unit for collecting, from each document server existing on the network, document property information of each electronic document stored in the document server and for constructing a document property table, and

wherein the view provider unit creates view information, referring to the access right database and the document property table, in which a group of electronic documents for which an access right is given to the user is classified based on the type of access right and based on the document property information.

9. A document distribution system for providing, to a user on a network, view information indicating information of a plurality of electronic documents on the network, the document distribution system comprising:

one or more document servers provided on the network for storing an electronic document and providing the electronic document in response to a request from a user; and

a document view providing device provided on the network for providing, to a user, view information indicating electronic documents which can be accessed by the user from among the electronic documents stored in the one or more document servers, wherein

the document server comprises an access right information storage unit for storing access right information indicating an access right given to each user for each electronic document which is stored in the document server, and

the document view providing device comprises;

an access right information collector unit for collecting access right information stored in the access right information storage unit of the document server and for constructing an access right database, and

a view provider unit for creating, in response to a request from a user, view information in which electronic documents for which an access right is given to the user is indicated classified based on the type of access right referring to the access right database and for proving the view information to the user.

10. A document distribution system according to claim 9, wherein

the view provider unit creates view information indicating a folder structure in which electronic documents corresponding to a type of access right given to the requesting user are placed in the folder for each corresponding type of access right.

11. A document distribution system according to claim 10, wherein
