The database Archivum Corporis Electronicum" allows access to the collection of squeezes, photographs and bibliographical references maintained by the CIL research centre, sorted by inscription-number. Digital images of inscriptions and squeezes (when available) can be viewed at different resolutions. Additions are made to the database continuously; the online version was last updated in December 2008.
Indices are available for those CIL volumes which currently lack a printed index. Available at present are a word-index to the Republican inscriptions (CIL I² 2, 4) and indices to the milestones from Raetia and Noricum (CIL XVII/4, 1). An index of find spots and places of storage for inscriptions from CIL I² 2-4 is currently being prepared for online use.
Concordances match the inscription numbers used in early editions (such as Gruter) to those of the Corpus Inscriptionum Latinarum; they are available as pdf-files. Also available are corrections and addenda to the Index Numerorum, the internal concordance to the CIL.
The Anthology is a selection of Latin verse inscriptions from Roman Africa, accessible via interactive maps, among other methods.
