is often difficult to find and retrieve for the average user so Greenpilot also aims to make access to these sources easier. The service addresses itself not only to scientists and students but also to the broadly interested public. Greenpilot has been modelled after the corresponding digital library for Medicine, Medpilot, also a project of the German National Library of Medicine. The ZB MED has chosen the slogan 'Greenpilot - all about life and science' as a motto. In Greenpilot scientifically relevant databases, library catalogues and websites can be searched by entering a search term and the results are presented in a standardised web interface.

. Functionally this is an expert search engine which centres around the intelligent semantic connection of search terms by means of a standardised vocabulary. This is made possible by Averbis's MSI software, which provides:
* semantic search optimised for the fields of Medicine and Life Sciences
* a contextual analysis of texts taking synonyms and compounds into account
* multilingual and cross-language search
* linking of lay and expert vocabulary
The search results are generated from a search index.
