"Scitopia.org, designed for direct access to the best in science and technology research, provides a one-stop search interface to more than three and a half million peer-reviewed articles and conference proceedings, fifty million patents, and full-text documents from government websites. Founded in 2007, scitopia.org spans 350 years of data, federating the scholarly content from twenty-one societies, and six government information sources. Each search is run against all or selected digital collections. Results are then aggregated, de-duplicated and ranked for maximum search efficiency." ( First mentioned in this blog, Oct. 23, 2008, as part of DTIC’s MultiSearch.)
Update: New alerting service
"Deep Web Technologies launches advanced alerts service in Scitopia.org – 06 Mar 2009
Federated search services provider Deep Web Technologies, US, has launched their advanced alerts service in Scitopia.org, the free, federated search portal powered by Deep Web Technologies’ Explorit Research Accelerator. Scitopia.org Alerts delivers science and engineering content of interest to users through email and RSS feeds automatically, rather than forcing users to come to scitopia.org to perform searches themselves. The service makes it easy for users to stay current on research from the deep web libraries of major science and engineering societies, such as IEEE, Institute of Physics, American Physical Society as well as patent databases and government sources."
"Scitopia.org Alerts service automatically runs searches requested by users on the terms and those societies they choose to include in their search. The technology “remembers” which search results have already been delivered to the user and sends only new results, making it a powerful tool for researchers to identify new publications and articles in their areas of interest. Alerts can be created for any term or field, including author, abstracts, and affiliations. The technology also recognizes institutional subscriptions to society content and automatically authenticates those users, allowing them to click through to the full text from the Alert. Others can purchase full text on a pay-per-view basis."
