The National Science Digital Library provides high quality online educational resources for teaching and learning, with current emphasis on the sciences, technology, engineering, and mathematics (STEM) disciplines—both formal and informal, institutional and individual, in local, state, national, and international educational settings.
The OpenScience Project contains a directory of open source scientific software. The computer science section lists resources under several categories including: algorithms and computational theory; artificial intelligence; data communication; human-computer interaction; languages; measurement and evaluation; simulation and modeling; software engineering; and symbolic and algebraic manipulation. A search engine is also included.
Developed by the NEC Research Institute and currently managed by Pennsylvania State University, CiteSeerx is a digital library and search engine for resources like journal articles, conference papers, and technical reports in computer and information science. In addition to a list of documents, an author or subject search automatically generates the search context and a list of related documents. The autonomous citation indexing feature executes a citation search similar to Science Citation Index or Scopus. Many of the citations are linked to the full text.
