Our goal is to make available computerized texts of as many Greek inscriptions as possible, from all areas and periods. This data bank of inscriptions is not intended to replace or reproduce printed editions: we do not attempt to reproduce the precise layout of printed texts, broken letters, critical apparatus, or commentary. The primary purpose of the data bank is to allow the texts to be searched as quickly and efficiently as possible by a variety of computers with appropriate programs.
(This text refers to the pre-2007 period when the database was available only via CD ROMs that required third-party software.)
