The Novi Commentarii was the second journal series of the St. Petersburg Academy, published in 21 volumes between 1747 and 1778. It had its origins in the publication delays from the predecessor journal, the Commentarii. Articles written over the course of the previous six years were bound together into two final volumes (13 and 14), and publication then passed to the Novi Commentarii. Euler published extensively in this journal, authoring 179 articles in total. Full scans of Novi Commentarii volumes can be found at the Biodiversity Heritage Library online.
