The Inscriptiones Graecae (IG) are an academic project originally begun by the Prussian Academy of Science, and today continued by its successor organisation, the Berlin-Brandenburgische Akademie der Wissenschaften. Its aim is to collect and publish all known ancient inscriptions from the mainland and islands of Greece. The project was designed as a continuation of the Corpus Inscriptionum Graecarum (Corpus of Greek Inscriptions, abbreviated CIG) published by August Böckh between 1825 and 1860, and as a parallel to the Corpus Inscriptionum Latinarum (Corpus of Latin Inscriptions) founded by Theodor Mommsen in 1847. From 1860 to 1902, it was directed by Adolf Kirchhoff. From 1902 to 1931, Ulrich von Wilamowitz-Moellendorff was in control of the project; he reorganised and re-energised the IG, turning it into one of the most important series for the publication of source material in classical studies. After the Second World War, the project suffered from a lack of financial and motivational support. It came to a temporary halt in 1972, but was revived by the newly reformed Berlin-Brandenburg Academy in 1994. So far, 49 fascicles have been published, some of them in several editions. The preparation of individual volumes is partially entrusted to external scholars, in which case the Berlin Academy retains the final editing.

The Corpus Inscriptionum Latinarum (CIL) is a comprehensive collection of ancient Latin inscriptions. It forms an authoritative source for documenting the surviving epigraphy of classical antiquity. The CIL collects all Latin inscriptions from the whole territory of the Roman Empire, ordering them geographically and systematically. The earlier volumes collected and published authoritative versions of all inscriptions known at the time—most of these had been previously published in a wide range of publications. The descriptions include images of the original inscription if available, drawings showing the letters in their original size and position, and an interpretation reconstructing abbreviations and missing words, along with discussion of issues and problems, all in Latin. The CIL presently consists of 17 volumes in about 70 parts, recording approximately 180,000 inscriptions. Thirteen supplementary volumes have plates and special indices. The first volume, in two sections, covered the oldest inscriptions, to the end of the Roman Republic; volumes II to XIV are divided geographically, according to the regions where the inscriptions were found. The other volumes cover other topics. Volume XVII, for instance, is entirely devoted to milestones. A volume XVIII is planned, which will contain the Carmina Latina Epigraphica (Latin verse inscriptions). A two-volume "Index of Numbers", correlating inscription numbers with volume numbers, was published in 2003. The Berlin-Brandenburgische Akademie der Wissenschaften continues to update and reprint the CIL in new editions and supplements.
