A technical, user and cost comparison study was undertaken to provide the Educational Resources Information Clearinghouse (ERIC) staff with data on silver halide, diazo, and vesicular type films for microfiche duplication. This information will allow ERIC to determine if diazo and/or vesicular films should be considered in producing ERIC duplicate microfiche. Technical considerations reviewed included film properties, such as resolution, density, contrast and definition, and production costs. User environment and archival film properties such as durability and permanence were studied and statistically valid user evaluation and technical tests run. In addition, relevant literature was reviewed and interviews with recognized authorities conducted. The conclusion was reached that both diazo and vesicular films should be considered for use in generating ERIC microfiche. There existed no serious reservations about image quality and user preference, and both types are attractive on a cost effective basis since a savings of approximately 27% results from their use.
