List of Academic Databases and Search Engines

This page contains a representative list of major databases and search engines useful in an academic setting for finding and accessing articles in academic journals, or in repositories, archives, or other collections of scientific and other articles. As the distinction between a database and a search engine is unclear for these complex document retrieval systems, see:

  • the general list of search engines for all-purpose search engines that can be used for academic purposes
  • bibliographic 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.

Famous quotes containing the words list of, engines, search, list and/or academic:

    Feminism is an entire world view or gestalt, not just a laundry list of women’s issues.
    Charlotte Bunch (b. 1944)

    America is like one of those old-fashioned six-cylinder truck engines that can be missing two sparkplugs and have a broken flywheel and have a crankshaft that’s 5000 millimeters off fitting properly, and two bad ball-bearings, and still runs. We’re in that kind of situation. We can have substantial parts of the population committing suicide, and still run and look fairly good.
    Thomas McGuane (b. 1939)

    You that do search for every purling spring
    Which from the ribs of old Parnassus flows,
    And every flower, not sweet perhaps, which grows
    Near thereabouts into your poesy wring;
    You that do dictionary’s method bring
    Into your rhymes, running in rattling rows;
    Sir Philip Sidney (1554–1586)

    Every morning I woke in dread, waiting for the day nurse to go on her rounds and announce from the list of names in her hand whether or not I was for shock treatment, the new and fashionable means of quieting people and of making them realize that orders are to be obeyed and floors are to be polished without anyone protesting and faces are to be made to be fixed into smiles and weeping is a crime.
    Janet Frame (b. 1924)

    An academic dialect is perfected when its terms are hard to understand and refer only to one another.
    Mason Cooley (b. 1927)
