      The Digital Libraries Initiative (DLI) project at the University of Illinois at Urbana-Champaign (UIUC) was one of six sponsored by the NSF, DARPA, and NASA from 1994 through 1998. Our goal was to develop widely usable Web technology to effectively search technical documents on the Internet. We concentrated on building the experimental Illinois DLI Testbed with tens of thousands of full-text journal articles from physics, engineering, and computer science, and on making these articles available over the Internet before they are available in print. Our DLI Testbed used document structure to provide federated search across publisher collections, by merging diverse tags from multiple publishers into a single uniform collection. Our sociology research evaluated the usage of the DLI Testbed by more than a thousand UIUC faculty and students. Our technology research moved beyond document structure to document semantics, testing contextual indexing of document content on millions of documents.
    • Federated Search of Scientific Literatures: A Retrospective on the Illinios Digital Library Project

      The NSF/DARPA/NASA Digital Libraries Initiative (DLI) project at the University of Illinois at Urbana-Champaign (UIUC), 1994-1998, had the goal of developing widely usable Web technology to effectively search technical documents on the Internet. The DLI testbed focused on using the document structure to provide federated searches across publisher collections. Our sociology research included the evaluation of its effectiveness under use by over 1,000 UIUC faculty and students, a user community an order of magnitude bigger than the last generation of research projects centered on searching scientific literature. Our technology research developed indexing of the contents of text documents to enable a federated search across multiple sources, testing this on millions of documents for semantic federation. This article will discuss the achievements and difficulties we experienced over the past four years.
    • Federating diverse collections of scientific literature

      Schatz, Bruce R.; Mischo, William; Cole, Timothy; Hardin, J.; Bishop, Ann Peterson; Chen, Hsinchun (IEEE, 1996-05)
      A University of Illinios project is developing an infrastructure for indexing scientific literature so that mutliple Internet sources can be searched as a single federated digital library.
