This search engine covers sources of parliamentary research service publications for the national parliaments of Austria, Germany and Switzerland, plus the German-language research publications of the European Parliament.
This search engine is in development. It was suggested by Diego Hättenschwiler of the parliament of Switzerland who has also provided essential guidance to the sources. Thank you, Diego.
NB most of the European Parliament German-language material is, so far, in translation from English original text.
This is an experimental tool and the results are not guaranteed to be comprehensive, especially as vocabularies and spellings vary; it also depends on how each study database is treated and ranked by Google. Precise results are more likely using tools on the individual sites.
