The purpose of these guidelines, which are based upon approved standards and practices, is to help insure the archival quality and the usefulness of the microfilm publications. Included are guidelines for: determining the suitability of a body of records for microfilming, arranging and processing the records, determining roll breaks, preparing insert pages, preparing special instructions to the camera operator, inspecting the negative film, and preparing a descriptive pamphlet. Since each body of records is unique, it is not possible to anticipate every problem concerning selection and preparation that might arise, therefore the guidelines should be considered as an aid not a set of binding rules.
