Justice is a perennial topic in scholarship on Romania, from socialist legality, through transitional justice, and into anti-corruption. Systematic study of law and justice has been stymied, however, by lack of basic information: who was doing what, where, when and how? To begin addressing this shortcoming this article introduces the Romanian Judicial Professions Database, a new, open-source tool which provides yearly, person-level data on 10,000 judges, 5300 prosecutors, 3000 notaries public (notari publici), and 1000 bailiffs (executori judecătoreşti), in some cases going back to the 1970s. To illustrate the utility of these new data, I derive a series of measures which address existing findings as well as open questions in four areas of research: the communist legal system, transitional justice, anti-corruption, and social stratification. The database can be downloaded at https://osf.io/gfjke/ and supporting code at https://github.com/r-parvulescu/ro_judicial_professions.
