The Ceramics Phase Diagrams Data Center faced several problems in the early stages of developing a computer data base to distribute to the ceramics user community. The Data Center had to create and store data files containing full scientific notation, provide for transferring data to undesignated computer(s) from the computer on which the files were created, and provide for installation of the data on undetermined Data Base Management System(s) for user access. The solution was incorporated in programs developed in the National Institute for Standards and Technology (NIST) Office of Standard Reference Data and expanded under the support of the American Ceramic Society. All information is expressed using only printable ASCII characters and is stored in dynamic arrays with all fixed length parameters encoded as program variables. Bibliographic and some chemical data for the next several volumes of Phase Diagrams for Ceramists are currently being stored in this form. The data are being manipulated to produce material in typeset form for the published volumes. They have also been transferred with no loss of information to a prototype data base for rapid retrieval.
