Literature Search: BASE Search Engine

BASE, a search engine operated by the Bielefeld University Library, indexes more than 240 million documents from over eight thousand content providers. About 60% of indexed documents are open access. Bielefeld Library staff evaluate content providers to ensure that their content meets scholarly standards. <

The sorting capabilities of BASE are far more powerful that similar tools like Google Scholar. BASE allows the user to filter results by author, title, subject, Dewey decimal number, year of publication, content provider, language, document type, access and terms of re-use. Users should notify the library if they are interested in obtaining articles for which no full text is available. The library can usually obtain these for patrons through inter-library loan within 24 hours.
