Beschreibendes Verzeichniss des Richard Wagner-Museums in Wien: ein bibliographisches Gesammtbild der kulturgeschichtlichen Erscheinung Richard Wagner's von den Anfängen seines Wirkens bis zu seinem Todestage den 13. Februar 1883

This descriptive catalog was compiled by the Austrian bibliophile Nikolaus Oesterlein and published in Leipzig in the late 19th century. Oesterlein was a dedicated collector of Wagneriana who established the Richard Wagner-Museum in Vienna, intending to create a comprehensive bibliographical record of the composer's life and artistic output. The work serves as a meticulous inventory of the museum's holdings, documenting everything from scores and librettos to personal correspondence and contemporary critical responses up to Wagner's death in 1883.

Oesterlein's design for the volume reflects the rigorous scholarly standards of 19th-century German archiving. By organizing the material chronologically and thematically, he sought to frame Wagner not just as a musician, but as a central figure in European cultural history. The catalog is highly regarded by musicologists and historians for its precision and scope, acting as a foundational resource for understanding the Wagner cult that developed during the late Romantic period.
