Summary

Digital libraries are an important source of many information queries and research areas. One of the main challenges defined by National Digital Library Program at the library of congress is to establish protocols and standards to facilitate the assembly of distributed digital libraries. From Internetworking point of view interoperability is an important issue.

The Stanford Digital Library Technologies Project goal was to design and implement the infrastructure and services needed for collaboratively creating, disseminating, sharing and managing information in a digital library context.

The CMU Digital Library architecture, like the Stanford initiative, is outcome of a DLI supported project. CMU's Informedia goal is to achieve machine understanding of video and film media, including all aspects of search, retrieval, visualization and summarization in both contemporaneous and archival content collections.

JournalServer is an Oxford-based international initiative to create a digital library of academic journals freely available to the public. It involves the collaboration of several leading universities across the world.
