Results of stable isotope analyses from 435 locations in the countries of the former USSR were collected from 114 papers presenting the results of their research and compiled in two datasets stored in the IsoArcH database. The literature research was conducted using Google Scholar, Web of Science and Science Direct using keywords both in English and in other relevant languages, such as Russian, Ukrainian, Azerbaijani, Georgian or Kazakh. The datasets contain information on the originating site, including GPS coordinates, information on the samples (as available) such as source of origin, dating and details of deposition, and results of stable isotope analysis, namely the measurements of carbon (&delta;<sup>13</sup>C), nitrogen (&delta;<sup>15</sup>N), oxygen (&delta;<sup>18</sup>O), sulphur (&delta;<sup>34</sup>S) strontium (<sup>87</sup>Sr/<sup>/86</sup>Sr) and lead (<sup>206</sup>Pb/<sup>204</sup>Pb). All source articles are connected to relevant data within the datasets. This compilation can serve as a comprehensive source for further research as well as a reference set for the geographical and temporal area.
