  • Search Box

    If you want to provide a search field for BASE searches on your website, simply add the following piece of source code to your home page:

    <form action="https://www.base-search.net/Search/Results" method="get" accept-charset="UTF-8">
    <input type="text" name="lookfor" style="width:200px;" maxlength="1024" />
    <input type="submit" value="Search BASE" />
    <input type="hidden" name="l" value="en" />
    <input type="hidden" name="refid" value="dcexternen" />
    </form>

    By using CSS you can customize the design of the search box, so that it fits your web site well. Be careful not to modify the code, it may affect the functionality.
  • Interface for Zotero
    Zotero is the name of a platform independent open source software for collecting, managing and citing various kinds of online and offline resources. It is available and useable as an add-on for the Firefox browser. To a large extent, the assumed functions of a classic reference management system are supported. After having installed the add-on you can transfer results from BASE to Zotero.

  • Integration of BASE into local infrastructures (API)

    For non-commercial purposes only you can integrate the BASE index via an API into your own local infrastructure (e.g. meta search engines, library catalogues). For the realisation we provide a HTTP interface. A manual is available for download:
    Download BASE Interface Guide

    Before you can start testing and using the HTTP interface, your IP address needs to be registered first. Please send us a short message.
  • BASE OAI Interface

    Project partners can retrieve the OAI metadata collected and normalized by BASE via an OAI-PMH interface.
    To get partners started quickly, we provide compressed dumps of our complete metadata as HTTP downloads.

    Before you can start testing and using the OAI interface, your IP address needs to be registered first. Please send us a short message.
  • Validate OAI Interface
    A service for repository managers: OVAL, the BASE OAI-PMH Validity Checker easily verifies if the OAI-interface is compliant with the BASE requirements.
  • OAI-PMH Blog
    Our OAI-PHM Blog communicates information related to harvesting and aggregating activities performed for BASE.
