With the high number and variety of archaeological sites entries, forming editorial and scientific committees is a natural organizational approach. For each archaeological period, there will be a scientific committee of one or two scholars with relevant specialization. Each committee has the responsibly to suggest site entries for inclusion into the Gazetteer, as well as (co-)author, solicit, collate, and edit site entries in their assigned field. They will also have the responsibility to communicate with other committees to produce site entries in cases where a single site spans multiple time periods. Seven committees can be envisioned at this point: The Prehistoric committee dealing with sites ranging in date from Paleolithic to Neolithic; the Bronze Age sites; the Iron Age sites and all that fall within Proto-historic times, including the sites associated with the Medes; the sites of the Elamite period; Achaemenid and Post-Achaemenid sites; Seleucid and Parthian sites; Sasanian and early Islamic sites. The following is a tentative list of committees and their members:
