In its new form since 1 January 2009, the Parliament Library is in fact the product of an eventful history. It resulted from the merger of the Federal Assembly Documentation Service’s library, part of the Federal Parliament and Central Library that was closed down under the reform of the federal administration in 2005-2007 and the library of the Federal Department of Foreign Affairs.
The premises now occupied by the Parliament Library are in fact the chamber where the National Council sat between 1858 and 1902. It was converted into a library after the new parliament building was completed and both Councils moved in 1902. As part of the renovation of the west wing of the parliament building in 2009, the library was once again transformed and renovated, valuable historical aspects being carefully preserved.
