Köchelverzeichnis (Köchel catalogue, original numbering)

Note that this series does not correspond with any specific Köchel catalogue.

While most of the numbers are from the first edition, there are many works which were not in the first edition, and so their original number was assigned in a later edition.

In particular, any number which includes a letter at the end (e.g. K. 315a) is likely to be from a later edition.
