Scirus Partners with Networked Digital Library of Theses and Dissertations, the World's Largest Theses and Dissertations Portal

Addition of NDLTD Expands Scirus' Coverage and Reflects the Increasing Value of This Unique Academic Content

AMSTERDAM, OCTOBER 5, 2005 - Elsevier today announced a landmark partnership between Scirus, its free science-specific search engine, and the Networked Digital Library of Theses and Dissertations (NDLTD) to add the extensive collection of theses and dissertations of its member institutes to Scirus. In addition to indexing the content on, Scirus will power a search service on the repository's site. The service will ensure this content will be easier to find on both the NDLTD and Scirus websites. The launch of the service was announced this week in Sydney at NDLTD's annual conference ETD2005.

"Until now, theses and dissertations have not been fully leveraged by postgraduate students and researchers in their work because these documents have been difficult to find and retrieve," said Deborah Kahn, an associate at Electronic Publishing Services, Ltd.

To combat this trend, Scirus has indexed over 200,000 theses and dissertations, in more than twelve languages, including English, Portugese, French, German, Spanish and Taiwanese, among others. The theses and dissertations are from institutes around the world, including their largest content contributors Library and Archives Canada, Hong Kong University, Brazilian Institute of Scientific and Technical Information (IBICT), MIT, University of Uppsala, National Sun Yat-Sen University of Taiwan (NSYSU) and Virginia Tech.

Adding to the growing success of Scirus' Repository Search service, the addition of NDLTD's impressive compilation of theses and dissertations supports Scirus' strategy to cover important and relevant scientific information. By providing full-text and fielded search capabilities on both Scirus and NDLTD's site, Scirus ensures users can easily search and find the information they need beyond web and journal content. Because the credibility of sources indexed in Scirus is of great importance to users, NDLTD results will be clearly branded and identified on the results page.

"Scirus continues to recognize and add new and relevant content sources and information types, often overlooked by other search engines," said Sharon Mombru, senior product manager of Scirus. "We are very pleased to be instrumental in making valuable and hard to find academic content more available to our users."

"With its particular expertise in indexing for scientific and research content, Scirus is a logical partner for NDLTD," said Edward Fox, executive director of NDLTD and professor of computer science at Virginia Tech. "Building on their impressive history of providing scientists and students with the information they need for their research, Scirus now also supports NDLTD's goals of enhanced access to scholarship worldwide. We are looking forward to expanding our collection and partnership in the future."
