The Verzeichnis der im deutschen Sprachraum erschienenen Drucke des 17. Jahrhunderts (in English: Bibliography of Books Printed in the German Speaking Countries from 1601 to 1700), abbreviated VD17, is a project to make a retrospective German national bibliography for the 17th century. The project was initiated in 1996 and planned to continue for 10-12 years. It is financed by the Deutsche Forschungsgemeinschaft (German Research Foundation). As of early 2007, the database contains more than 250,000 titles.
There is a corresponding German national bibliography for the 16th century, known as VD 16, which was compiled during the period 1969-1999, and another for the 18th century is planned.
