Problems exist with the accumulation of large amounts of data, their preservation, and the sharing and coordination of this information. Two examples of ceramic studies are given whereby this accumulation of data has provided new insights into the ceramic technologies of Greece and of Meso-America. An example of clay provenance is also cited. The use of established data management programs assumes a basic structure to the information which is entered; in an archaeometric data bank, the search may be for a structure which is not initially known to exist. A difficulty with sharing this information among related agencies will be the format; different standardization of entry can be made compatible. A central agency for overseeing the data that have been generated is necessary for their preservation and dissemination. -- AATA
