The research on Old Turkic runiform sources reaches back to several generations of scholars, who collected valuable knowledge about their signs, paleography, spelling and grammar. They are an important part of the written heritage of the Turkic world, providing us with valuable linguistic and historic information. Taken together, these inscriptions constitute a large corpus of several hundred inscriptions. However, there have never been systematic activities aimed at documenting the Altai corpus as a whole until very recently.
