The NASA Technical Report Server (NTRS) is now based on the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH). This metadata harvesting version of NTRS represents a significant improvement over the previous distributed searching implementation of NTRS. In addition to being an OAI-PMH service provider, the new version of NTRS is also an OAI-PMH aggregator. This allows NTRS to serve as a one-stop shop for harvesting of NASA metadata.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
