BASE (Bielefeld Academic Search Engine) is a highly comprehensive search engine that specializes in academic web resources. It is managed by Bielefeld University Library and offers access to over 300 million documents from more than 10,000 content providers. Nearly 60% of these documents are freely accessible in entirety due to open-access policies.


The resources indexed by BASE are academically relevant and include journals, digital collections, and institutional repositories that have an OAI interface and use OAI-PMH to provide content. The service is continuously updated with new sources and content providers. What makes BASE over commercial search engines is the careful selection process used to identify content providers, which involves the assessment of the academic quality and relevance of the documents they provide. This ensures that only high-quality and relevant content is included in the index.


BASE also offers several features that enhance the search experience. For example, the search interface is multilingual, allowing users to search for content in over 20 languages. The search results display precise bibliographic data, and users can sort the results list by author, title, or date. Author, subject, year of publishing, content provider, language, document type, access, and re-use terms can also be used to filter the results.
