CiteSeerx is an evolving scientific literature digital library and search engine that has focused primarily on the literature in computer and information science. CiteSeerx aims to improve the dissemination of scientific literature and to provide improvements in functionality, usability, availability, cost, comprehensiveness, efficiency, and timeliness in the access of scientific and scholarly knowledge. Rather than creating just another digital library, CiteSeerx attempts to provide resources such as algorithms, data, metadata, services, techniques, and software that can be used to promote other digital libraries. CiteSeerx has developed new methods and algorithms to index PostScript and PDF research articles on the Web.

The Digital Commons Network provides free access to full-text scholarly articles and other research from hundreds of universities and colleges that use the Digital Commons repository platform. Curated by university librarians and their supporting institutions, this dynamic research tool includes peer-reviewed journal articles, book chapters, dissertations, working papers, conference proceedings, and other original scholarly work.

The DOAJ is both a directory and searchable database of open access journals. The directory can be browsed by broad subject categories.

Engineering Library provides access to a multitude of public-domain engineering resources available in one convenient location. We tracked down these valuable references and converted them into easy-to-read web pages because the team at Engineering Library believes that engineers should have access to a comprehensive, well-organized library, and it is our goal to provide that.

Provides users with a single access point to a broad range of topics across many disciplines and many types of information resources including journal and conference articles, books, reports, theses and government publications. Note that many of the results from a Google Scholar search will not be freely available.

The name ROSA P was chosen to honor the role public transportation played in the civil rights movement, along with one of the important figures, Rosa Parks. Founded as an all-digital library program, NTL's collection in ROSA P are full-text digital publications, datasets, and other resources. Legacy print materials that have been digitized are collected if they have historic, technical, or national significance. The repository is also designated as the full-text repository for USDOT-funded research the USDOT Public Access Plan. Collections in ROSA P are available without restriction to transportation researchers, statistical organization, the media and the general public.
