In this volume fifteen musicologists from five countries present new findings and observations concerning the production, distribution and use of music manuscripts and prints in seventeenth-century Europe. A special emphasis is laid on the Düben Collection, one of the largest music collections of seventeenth-century Europe, preserved at the Uppsala University Library. The papers in this volume were initially presented at an international conference at Uppsala University in September 2006, held on the occasion of the launching of _The Düben Collection Database Catalogue_ on the Internet. For the first time, the entire collection had been made acessible worldwide, covering a vast number of musical and philological aspects of all items in the collection.
