Abstract
This article describes the off-line retrieval systems for the data base file of literatures on dental materials and devices which was constructed by the Japanese Society for Dental Materials and Devices.The off-line systems employed two kinds of commercially available softwares for data base management on a personal computer.The data base file was stored in the large-scale computer and downloaded into MS-DOS text files.They were supplied through floppy disks.A program was developed for converting the text files into coded data format which could be transmitted to the applied software.The converted data base files could be successfully processed with two commercial softwares for data base management on a personal computer.
