The mode of universal access for information seeking and knowledge acquisition differs greatly fi'om the traditional ways. From the information resources point of views, the old model of“owning” a collection has given way to “sharing,” and the new emphases have shifted fi'om possessing large “physical libraries” to “virtual libraries” digitally distributed all over the world. “Universal access” has taken on a very different meaning when one has the ability to share invaluable resources through the use of cutting edge technologies. The author has experienced much of these transformations through her own R&D activities-from the creation of interactive videodisc and multimedia CD on the First Emperor of China's terracotta warriors and horses in the 1980s and 1990s to leading a current international digital library project, Global Memory Net (GMNet), supported by the US National Science Foundation. In presenting her vision for linking world digital resources together for universal access, she will share with the audience the latest development of Global Memory Net.展开更多

Here we propose a new service architecture suitable for integra- tion and sharing of distributed multi-source geographic information. We also propose a global virtual pyramid model, which can be applied in 3D virtual globes. In view of the difficulty of web multi-node geographic information sharing service, we propose a web multi-node service aggregation method, integrated in our autonomously developed virtual globe platform Geo- Globe and introduced in the National Platform for Common GeoSpatial Information Services named "T1ANDITU". It achieves 2D and 3D integration for geographic information service.展开更多
