The MPI-Mainz-UV-VIS Spectral Atlas is a comprehensive collection of absorption cross sections for gaseous molecules and radicals, primarily relevant to atmospheric research, from measurements performed during the last nine decades. The individual data sets were collected from the original publications, either copied from tabulations, or read from figures in those cases where numerical data could no longer be obtained. Other sources rely on the internal databases of several research centers dealing with atmospheric chemistry and/or molecular spectroscopy. Numerous excellent high-resolution spectra were obtained from personal communications with the scientists.

The bimonthly newspaper Za vozvrashchenie na Rodinu ("Return to the Motherland") was published between 1955-1960 in East Berlin, primarily aimed at Russian emigrants in the West.

The main objective was to create a favorable image of the Soviet Union and to criticize émigré organizations in the post-war period. During its publication, the newspaper was not available to the public on a subscription basis, therefore it has become a rare information resource.
