“The Global Science Gateway,” is operated by the Office of Scientific and Technical Information—a branch of the Office of Science within the U.S. Department of Energy. The site utilizes databases from over 70 countries. When users type a query, it hits databases from all over the world and will display both English and translated results from related journals and academic resources.

Operated and maintained by the Office of Science and Technical Information, the same department that collaborates on WorldWideScience.org. This search engine pulls from over 60 databases, over 2,200 websites and 200 million pages of journals, documents and scientific data. Search results can be filtered by author, date, topic and format (text or multimedia).

A self-described “computational knowledge engine,” Wolfram Alpha does not so much provide search results as it does search answers. Simply type in a topic or question you may be interested in, such as, “What is the function of the pancreas?” and the answer will show up without making you scroll through pages of results. This is especially handy for those in need of math help.

With its minimalist design, Refseek doesn’t look like much. However, the engine pulls from over one billion web pages, encyclopedias, journals and books. It is similar to Google in its functionality, except that it focuses more on scientific and academic results—meaning more results will come from .edu or .org sites, as well as online encyclopedias. It also has an option to search documents directly—providing easy access to PDFs of academic papers.

Describes itself as a “Google-alternative safe search engine.” This academic search engine pulls from results that have been curated by librarians, teachers and other educational workers. A unique search feature allows users to select a category, which ranges from art to health to science and technology, and then see a list of internal and external resources pertaining to the topic. So if you don’t find what you’re looking for within the pages of Infotopia, you will probably find it in one of its many suggested sites.

This site is perfect for those studying anything related to healthcare or science. PubMed Central is operated by the National Center for Biotechnology Information, a division of the U.S. National Library of Medicine. The database contains more than 3 million full-text journal articles. It’s similar to PubMed Health, which is specifically for health-related research and studies, and includes citations and abstracts to more than 26 million articles.
