This is a scientific literature digital library and search engine that focuses primarily on the literature in computer and information science. CiteSeer aims to improve the dissemination and feedback of the scientific literature and to provide improvements in functionality, usability, availability, cost, comprehensiveness, efficiency, and timeliness in the access of scientific and scholarly knowledge.
The arXiv is a permanent, freely available digital library of research articles (or e-prints) in physics, mathematics, computer science, and quantitative biology maintained at Cornell University. It was started in 1991 at Los Alamos in the area of high-energy theoretical physics and was then known as hep-th; for many years it was also known as "xxx". The Front for the arXiv is an overlay maintained at UC Davis by Greg Kuperberg.
"The Math Forum is a leading center for mathematics and mathematics education on the Internet. Operating under Drexel's School of Education, our mission is to provide resources, materials, activities, person-to-person interactions, and educational products and services that enrich and support teaching and learning in an increasingly technological world."
A global directory/catalog of research data repositories covering all academic disciplines. Search by topic or keyword to find a database relevant to your project. re3data recently merged with Databib -- all information from both systems is now available through the re3data site. The combined new service will be managed under DataCite.
This institutional repository is a service of the University of Denver Libraries. Research and scholarly output included here has been selected and deposited by the individual university departments and centers on campus.
