Ways in which computers and audio tape recorder techniques were used to record, index, and present data collected during two summers of field work in a rural area of Mexico are described. The research goal was to study the Otomi Indian shamans. Two computers were used: the Honeywell 6800 DPS-2 and the Osborne-1 microcomputer. The database system chosen for the project was the Lister system for Honeywell computers operating under the Multics operating system. The Lister system, which has many of the requirements important for an ethnographic database, e.g., flexibility in formatting data and ability to store both qualitative and quantitative data, is described. The field work was paperless. Interviews were recorded on audio-cassettes and then abstracted and typed into the field computer. Field notes and translations of the shaman interviews were entered and edited on the field computer. The information was then transferred by phone line from the microcomputer disks to the large computer. An index of the abstracts was made by the large computer. Appendices, which comprise the bulk of the report, discuss computer processing details, the Lister database, and the computer programs used. (RM)
