Selecting subject specific records from the Bielefeld Academic Search Engine (Part 1)
Introduction Since 2004, the Bielefeld Academic Search Engine (BASE) offers an aggregated metadata search over scientific publications. By indexing well over 300 million records (60% of which are open access1) from almost 10,000 international repositories, it provides researchers with an invaluable access to publications. In addition to offering a VuFind based discovery system, the aggregated data is also available via both a live search API and an OAI-PMH interface to enable re-use by 3rd party services.
