The Corpus Inscriptionum Latinarum (CIL), a rather comprehensive collection of Latin inscriptions throughout the Roman world, is hosted online by the Berlin-Brandenburg Academy of Sciences and Humanities. According to the announcement at Arachne:
This digitized version of the CIL will initially comprise of the more than 50 parts (of vols. I-XVI + auctaria and of v. I (edition altera)) published before 1940. Available funding covers the digitization of the volumes with an imperfect OCR searching capability. The goal is to eventually create a keyword searchable database to contain also future volumes of the CIL as they fall outside of copyright restrictions and to eventually do the same for the Inscriptiones Graecae.
Nice to see such important resources online.Via http://hypotyposeis.org/weblog/2012/08/corpus-inscriptionum-latinarum-cil-online.html
