Find publications on typefaces, compile catalogues by decade, find out which typefaces were used most often, and locate the state measures that selected them — a list of what was kept and what was discarded.
Perplexity gathered sources; from them, a brief for Deep Research was built in my prompt-writing project; ChatGPT compared type standardisation in the USSR, the USA, Britain, France and Germany up to 1953. Found the OST 1337 and GOST 3489 standards and Bormann’s 1941 circular banning Fraktur.
