Catalog and Digitals

It should be stated at the outset that no catalogue of Joseph Haydn's works has existed to date that offers both a systematic and a chronological ordering of his immense output according to strict scholarly criteria.

Even the catalogue compiled by Anthony van Hoboken from 1957 onwards, which remains valid to this day, represents, put simply, an attempt to transfer his collection of early and first editions of Haydn's works onto a system of ordering that did not exist before and which he had to develop specifically for this purpose.
