File (or Copy) Type

During a digitization project, several types of digital files that serve different purposes and intents may be created. The Digitization Services Branch creates master files to certain specifications and standards for most digitization projects. Master files are generally of high quality, carry forward important information or aspects of the original record, are maintained over the long term, and are used to make additional copies for distribution and use. The Digitization Services Branch staff create two types of master files (in general, only one type of master file will be created per project, although in some cases, both types may be created):

As mentioned above, master files are then used to create a variety of Distribution Copies for specific uses and purposes, such as files submitted to NARA's Archival Research Catalog (ARC) for online access, use in various print and electronic publications, and use on easily distributed and portable media for reference purposes.

A simplified Current Format Summary is also available.
