ABSTRACT
This paper outlines many of the issues involved in the analytical description of sources gathered in the preparation of the Rossini thematic catalog. The compilers are committed to examining every publication of Rossini’s operas, either in full score or in reductions for voice and piano. However, except in very special cases, no attempt will be made to provide information about arrangements or adaptations. The central focus of the catalog is the establishment of information pertaining to the authentic versions and authentic sources for each composition.
