摘要:The important role of directories in the national resource sharing infrastructure is addressed and the goals and activities of the National Library's Directories Project are described. This Project has three components: the new online version of the Interlibrary Resource Sharing Directory (ILRS); the application of X.500 to the ILRS for the PRIDE Project; and the revision of ISO2146, the international standard for library directories. The new ILRS will have improved integration with Kinetica and LIDDAS, the key national resource sharing systems.
