When you search for energy-related documents at the OSTI Information Bridge database, your search results now generate clusters of authors and subjects related to your query. So you get a list of full-text documents to download plus a list of authors doing related work and a list of subjects on related research. These lists are linked, leading to additional full-text documents related to your search query, allowing deeper exploration of your topic. Information Bridge provides free public access to over 200,000 full-text documents and bibliographic citations of Department of Energy research report literature. Documents are primarily from 1991 forward and were produced by DOE, the DOE contractor community, and/or DOE grantees. Legacy documents are added as they become available in electronic format.
