This was the first journal series published by the St. Petersburg Academy. Its publication eventually ran to 14 annual volumes, of which Euler published in numbers 2-14. The publication delay for each volume was often quite long: a volume's official year could lag up to 10 years behind the actual year it was printed. Full scans of Commentarii volumes can be found at the Biodiversity Heritage Library online.
Successor Journal: Novi Commentarii.
