Which series of RISM is arranged by composer and printed music?

The series of RISM (Répertoire International des Sources Musicales) that is specifically arranged by composer and focuses on printed music is Series A. This series serves as a critical cataloging resource that organizes and provides access to printed music through the lens of individual composers, making it easier for researchers, musicians, and historians to locate works by specific individuals.

In the context of RISM, Series A includes printed music published before 1800, which is vital for historical research in musicology. The structured approach of this series not only highlights the works of composers but also aids in the study of the evolution of print music and its dissemination during that period.

Other series in RISM, such as B, C, and D, cover different aspects of music sources, such as manuscripts or specific types of collections, but do not specifically focus on composer arrangement in the way Series A does. This distinction reinforces the significance of Series A as an indispensable tool for exploring the print music legacy of composers.
