Unlackable Information of Grey Documents Resources
Ping Zhang · 2009
Grey decuments have plenty of contents and many kinds,they are unlackable information resources among the documents resources’ construction, amd have a great function for people’s political and economical life. It is earlier to develop the grey docluments abroad, and their area is broader, it is worthy for us to draw on their experiences. We should improve our recogmition, strengthen our management and cooporation, and share the resources with others, develop and make full use of the grey documents.
