42、f First-Generation, Silver Microforms of Documents.) The original ANSI/AIIM MS23-1981 was a combination and a revision of the two National Micrographics Association (NMA) Recommended Practices: Operational Procedures for the Production of Microforms NMA MS110-1974; and Inspection and Quality Control
43、 of First-generation Silver-Halide Microfilm NMA MS104-1972. ANSI/AIIM MS23-1983 updated the 1981 version, and the 1991 revision is the result of the most recent review process. In 1993, the AIIM Quality Control Committee, C10, decided to completely redesign MS23 into a document that was more tutori
44、al in nature. Throughout the document, references will be made to specific and appropriate standards. This revision results from a reexamination of the purpose, scope, and content of the previous standard with a view towards providing technical guidance in the identification, measurement, and evalua
45、tion of quality levels in first-generation silver microforms. The developers of this revision seek to emphasize that overall quality of a microform product involves many factors. The document discusses these factors, identifies quality procedures, and provides a means to measure the end product in t
46、erms of its suitability to serve an identified purpose. The flowchart in (informative) annex A lists many of the essential factors that are necessary to develop and maintain a successful micrographics operation for its intended purposes. Certain international, federal, state, and local regulations m
47、ay require compliance with this document. Many specific uses of microfilm, especially those that involve the microfilming of poor-contrast documents or image digitization, might require higher levels of quality than are indicated in this standard. However, certain minimum standards should be maintai
48、ned to ensure that microfilm quality is adequate for general use. This document identifies minimum quality requirements suitable for most source documents. (Technical specifications, quality levels, targeting requirements, and formatting requirements for microfilm to be scanned or digitized can be f
49、ound in preservation microfilming documents published by the American Library Association and The Research Libraries Group.) Blank forms for use during inspection are included in (informative) annex B and may be copied and used. Suggestions for improving this standard are welcome. They should be sent to the Chair, AIIM Standards Board, Association for Information and Image Management International, 1100 Wayne Avenue, Suite 1100, Silver Spring, Maryland, 20910-5603.
