The database primarily compiles data from 19th-century Viennese music and theater journals. The analysis (1979–2003, 2007–2008) deliberately focused on ‘Vienna’ and ‘Austria’. A complete and exhaustive collection was not attempted. Given the project’s extended duration and varying contributors, the data quality is inconsistent.

In the creation of this MySQL database (2013), the spelling of names and places were largely standardized. The database provides information on persons, works, places, and terms, with some entries offering more extensive excerpts.
