List of academic databases and search engines the general list of search engines for all-purpose search engines that can be used for academic purposesbibliographic databases for information about databases giving bibliographic information about finding books and journal articles. Note that "free" or "subscription" can refer both to the availability of the database or of the journal articles included. This has been indicated as precisely as possible in the lists below. OpenDOAR Search Repository Contents This service, based on the Google Custom Search engine, lets you search the contents of the repositories listed in OpenDOAR for freely available academic research information. This quality assured approach minimises (but does not eliminate!) spurious or junk results, and leads more directly to useful and relevant information.

DART-Europe is endorsed by LIBER (Ligue des Bibliothèques Européennes de Recherche), and it is the European Working Group of the Networked Digital Library of Theses and Dissertations (NDLTD). The DART-Europe partners help to provide researchers with a single European Portal for the discovery of Electronic Theses and Dissertations (ETDs), and they participate in advocacy to influence future European e-theses developments. DART-Europe offers partners a European networking forum on ETD issues, and may provide the opportunity to submit collaborative funding applications to achieve DART-Europe's vision for ETDs. DART-Europe is resourced through partner contributions.
Simulations back up theory that Universe is a hologram Artist's impression by Markus Gann/Shutterstock At a black hole, Albert Einstein's theory of gravity apparently clashes with quantum physics, but that conflict could be solved if the Universe were a holographic projection. A team of physicists has provided some of the clearest evidence yet that our Universe could be just one big projection. In 1997, theoretical physicist Juan Maldacena proposed1 that an audacious model of the Universe in which gravity arises from infinitesimally thin, vibrating strings could be reinterpreted in terms of well-established physics. The mathematically intricate world of strings, which exist in nine dimensions of space plus one of time, would be merely a hologram: the real action would play out in a simpler, flatter cosmos where there is no gravity.
OAIster Access to OAIster A freely accessible site for searching only OAIster records is available at Additionally, OAIster records are fully accessible through WorldCat.org, and appear as WorldCat.org search results along with records from thousands of libraries worldwide.

Contributing to OAIster The OAIster database is included in WorldCat and metadata harvesting goes through the WorldCat Digital Collection Gateway.
Obamacare is having one huge success nobody knows about People are, rightly, upset about all that's going wrong with the president's health-care law. But something unexpected is going very, very right. (Mark Wilson / GETTY IMAGES) The background here is that before the rollout of the Affordable Care Act there were a lot of people eligible for Medicaid who simply didn't know it.
