As the open access movement grows and prospers, more and more repository servers come into being which use the "Open Archives Initiative Protocol for Metadata Harvesting" (OAI-PMH) for providing their contents. BASE collects, normalises, and indexes these data. BASE provides more than 70 million documents from more than 3,000 sources.

BASE is a registered OAI service provider and contributed to the European project "Digital Repository Infrastructure Vision for European Research" (DRIVER). 

In comparison to commercial search engines, BASE is charcterised by the following features:

• Intellectually selected resources
• Only document servers that comply with the specific requirements of academic quality and relevance are included
• A data resources inventory provides transparency in the searches
• Discloses web resources of the "Deep Web", which are ignored by commercial search engines or get lost in the vast quantity of hits.
• The display of search results includes precise bibliographic data
• Several options for sorting the result list
• "Refine your search result" options (by author, subject, DDC, year of publication, collection, language and document type)
• Browsing by DDC (Dewey Decimal Classification) and document type.
