Vertrag zwischen Tobias Haslinger und Graf Ferdinand von Troyer im Auftrage des Erzherzogs Rudolph über den Erwerb der handschriftlichen Prachtsammlung Beethovenscher Werke vom 20. September 1823, Abschrift

The so-called Haslinger-Rudolph copy is a complete collection consisting of 62 volumes. They contain all published Beethoven compositions that the composer complemented with a handwritten confirmation of authenticity. As a source it only has calligraphic value.

"The copying process was started in the fall of 1817 in relation with plans for a complete edition on Beethoven's compositions. It should contain all works Beethoven had published as prints, including all occasional compositions and pieces composed during his youth. (...) in 1821 the copying process, done by Matthias Schwarz, the dancing master of the Vienna Apollo Hall (score) and calligrapher Friedrich Warsow (title sheets) came to a temporary stop. Back then the edition already comprised 51 volumes. It was offered for sale - an event of national importance. When England raised an interest in purchasing the volumes, Archduke Rudolph decided to buy it in September 1823 for a price of 4,000 florins. In the following years, Rudolph had it be completed. (...) Close comparisons in relation with the new complete edition of Beethoven's works published by the Beethoven-Haus showed that the Haslinger-Rudolph copy is - with some exceptions - only of limited source value. Beethoven did not review it and the templates used were mainly printed editions, however, not the original ones.
