The online catalogue (OPAC) lists all of the printed books, articles and scores in the library’s holdings as well as a complete Mozart bibliography. Works that have already been digitalized may be accessed directly via a link.

The online catalogue lists the following holdings:

– modern and historical books and journals
– the Mozart Bibliography (books and articles on Mozart)
– the collection of historical librettos from the eighteenth and nineteenth centuries relating to works by Mozart and other composers
– historical and modern editions of works by Mozart (practically complete); at present only a fraction of works by other composers is included here.

Works that are not listed in the online catalogue may be found via the library’s internal catalogues. The library staff will be happy to help you here.
Scores by composers that were acquired before around 1998 are listed in the Répertoire International des Sources Musicales (Library siglum: ‚A-Sm‘)

Since the middle of the nineteenth century the Mozarteum Foundation’s most valuable holdings have been letters and documents as well as autograph scores relating to the Mozart family. The library holds more than half of all known documents associated with the family, including around 200 of Mozart’s original letters (he himself is the main contributor to 150 of these and one of multiple contributors in the case of the other fifty), around 300 letters written by his father Leopold and more than 100 autograph music manuscripts, most of them sketches and drafts of Mozart’s works in addition to autographs in the hand of Franz Xaver Wolfgang Mozart. The collection also includes scores, letters and other documents relating to numerous other figures from the eighteenth to the twentieth centuries. We are working hard to catalogue these holdings as part of various ongoing projects.
The basement of the building in which the Mozart family lived houses the vault containing these autograph treasures as well as an exhibition space that may be visited as part of special guided tours.

The Bibliotheca Mozartiana’s holdings are being systematically digitalized. Our aim is to grant free access to the priceless originals in the form of manuscripts, scores, books and so on in as simple a way as possible. To this end the portal “Bibliotheca Mozartiana digital” has been established. This helps users to locate the digitalized treasures and then to view them and, if necessary, to download them as pdf files.

The online Mozart Bibliography lists writings on Mozart from all over the world and is based on data from the Mozarteum Foundation’s Bibliotheca Mozartiana catalogue. It includes monographs, newspaper articles, reviews, electronic publications and concert notes that contain factual information relating to Wolfgang Amadé Mozart, his family and his circle.
