Short answers, pulled from the story.
The Corpus Inscriptionum Latinarum was formally founded in 1853 by Theodor Mommsen, within the organization now known as the Berlin-Brandenburg Academy of Sciences and Humanities. A preparatory committee had been created in Berlin in 1847, with Mommsen as its leading figure.
The Corpus Inscriptionum Latinarum currently records approximately 180,000 inscriptions. The collection consists of 17 volumes in about 70 parts, with thirteen supplementary volumes containing plates and special indices.
The first volume of the Corpus Inscriptionum Latinarum appeared in 1863, roughly sixteen years after the Berlin committee was first convened in 1847.
The collection orders inscriptions geographically and systematically. Volume I covers the oldest inscriptions up to the end of the Roman Republic. Volumes II through XIV are divided by geographic region, covering areas from the Iberian Peninsula and Britain to Africa and Rome itself. Other volumes are organized by topic, such as military diplomas in Volume XVI and milestones in Volume XVII.
Each entry includes images of the original inscription where available, drawings showing the letters in their original size and position, and an interpretation that reconstructs abbreviations and fills in missing words. Discussion of editorial problems is also included. The entire collection is written in Latin.
Yes, the Berlin-Brandenburg Academy of Sciences and Humanities continues to update and reprint the collection. Recent Auctarium Series Nova volumes appeared in 2021, 2022, 2023, and 2024. A future Volume XVIII is planned to contain the Carmina Latina Epigraphica, the Latin verse inscriptions.
