Science and Academic
(Scholarly Paper search engines now have their own page)ScienceResearch.com — Searchable access to scientific journals and databases.
Academic Index – Main search is a filtered Google search aimed at high authority rank sites, mainly .edu and .gov which filters a great deal out. Second search ties into deep web academic and non-academic databases skewed to librarians and educators.
Science.gov — Gateway to science info provided by US government agencies.
VideoLectures.net – Phenomenal video lecture coverage from high authority rank sources. A great go-to place to find peer-reviewed, conference presented, in depth coverage of a topic at a conference. A nice bonus, is the presentation slides are shown separately, and you can jump to slides of interest to you. Heavily technology based, and 66% is in English. Most lectures 45 minutes or longer.
WebCASPAR — A horrible interface to an alleged wealth of statistical info on science and engineering. I found the site slow, cludgy and designed around 1965 run off of candle power. From their website:”The WebCASPAR database provides easy access to a large body of statistical data resources for science and engineering (S&E) at U.S. academic institutions. WebCASPAR emphasizes S&E, but its data resources also provide information on non-S&E fields and higher education in general. ”
The Complete Work of Charles Darwin — Charles Darwin’s published works, search-able and available online. He’s still old and his works still ramble. Scanning didn’t help him much.
USGS Real-Time Water Data — Real-time map of streamflow and water quality data of the USA’s rivers and reservoirs.
USGS Earthquake Hazards Program — Showing real-time earthquake data. Focus on US but covers world as well.
IEEE Publications (Commercial) — Contains over 1.4 million documents from the Institute of Electronics and Electrical Engineers.
Society of Petroleum Engineers Archive (Commercial) — Petroleum engineers technical papers.
Arxiv – arxiv.org/ — Cornell University repository. Access to 700,000+ technical papers on everything from quantitative biology to computer science. Appears to offer full text in several formats.
VADLO – www.vadlo.com/ — Life Science Search Engine. Very hit and miss. Don’t have high expectations.
Deep Dyve (Commercial) — www.deepdyve.com DeepDyve has aggregated millions of articles across thousands of journals from the world’s leading publishers, including Springer, Nature Publishing Group, Wiley-Blackwell and more. Haven’t paid the premium to give it a test ride, if someone has, please write a review below.
