In the section entitled Moldenhauer No. (Moldenhauer numbers) the Knora/SALSAH platform provides a list of Webern’s complete works arranged according to their Moldenhauer numbers. Hans Moldenhauer made a chronological index of works and, with a few exceptions, attributed a number to each work known to him, regardless of whether it was part of a larger work or a piece in its own right. Despite harbouring occasional doubts as to its chronological accuracy, the AWG has taken over this numbering system which serves as a basis for the structuring of Webern’s oeuvre, but has however taken the liberty of extending or modifying it as required. The AWG has attributed a new number to pieces not included by Moldenhauer, irrespective of their chronology. These new numbers begin at 400, so as to clearly differentiate them from the original Moldenhauer numbering system, which runs to 347.

For each number there is an entry with brief information about the origins of the work and, where appropriate, its first performance and/or publication, as well as an outline of its various sources. References to a broader scheme within the context of the composer’s other works and the differing versions of a given work etc., are indicated via links (this area is still being developed and is regularly extended and supplemented).
