Updated regularly. As of December 2011, NLM Gateway only provides search access across two databases: Meeting Abstracts and Health Services Research Projects in Progress (HSRProj). Meeting Abstracts contains selected abstracts from meetings and conferences in the subject areas of AIDS, Health Services Research, and Space Life Sciences. Meeting Abstracts will remain accessible but will not be updated after 2011. HSRProj contains descriptions of research funded by federal and private grants and contracts and provides access to information about health services research in progress before results are available in a published form. Please see NLM's project description for a table that lists the names and URLS of NLM resources no longer available via NLM Gateway.
