Since starting the Mapping the Lives project in 2007, any discrepancies noticed in other databases have been noted and forwarded to the persons and institutions responsible for them, that they might correct any errors and make any necessary changes based on the newly discovered information provided. A number of good working relationships have been established, with the informal agreement to mutually share information when possible.

One major benefit as a result of this cooperation is the increase in the quality of data for all involved. Literally thousands of corrected names, places, dates of birth etc. have resulted from these information exchanges, identifying survivors who had been incorrectly listed as having died, as well as adding hundreds of people to the German national Memorial Book of Shoah victims who had not thus far been identified and properly memorialized.

Here is a partial list of institutions and companies to whose staffs we wish to offer grateful thanks for their active support and helpful cooperation:

The Federal German Archives Memorial Book (Bundesarchiv Gedenkbuch), The Jewish Monument Community of the Netherlands, the Museum project Silent Heroes Memorial Center (Gedenkstätte Stille Helden), the Berlin Coordination for the Stolperstein Project, the Freie Universität Berlin project Women Doctors in Imperial Germany (Ärztinnen im Kaiserreich), the Hamburg University project Lexicon of persecuted Musicians in the Nazi Era (Lexikon verfolgter Musiker und Musikerinnen der NS-Zeit), the Nazi-looted books project at the Central and Regional Library of Berlin (Zentral- und Landesbibliothek Berlin), and
