Between 1946 and 1987 the International Association for Classical Archaeology (AIAC) published the Fasti Archaeologici. It contained very useful summary notices of excavations throughout the area of the Roman Empire. However, spiraling costs and publication delays combined to render it less and less useful. AIACs board of directors thus decided in 1998 to discontinue the publication and to seek a new way of recording and diffusing new results. The Fasti Online is the result of this effort. The aim of the site is to provide a database of excavations since 2000, providing a record in English and in the local language for each season. We do not pretend to offer information on all sites being excavated, and certainly not on those excavated in the past, or never excavated. Each participating country is responsible for uploading the data it gathers: some countries’ records are more complete than others.
