Digital reformatting is the process of converting analogue materials into a digital format as a surrogate of the original. The digital surrogates perform a preservation function by reducing or eliminating the use of the original. Digital reformatting is guided by established best practices to ensure that materials are being converted at the highest quality. ==Imaging Standards== The Library of Congress has been actively reformatting materials for its American Memory project and developed best standards and practices pertaining to book handling during the digitization process, scanning resolutions, and preferred file formats.〔Library of Congress. (2007). Technical Standards for Digital Conversion of Text and Graphic Materials. http://memory.loc.gov/ammem/about/techStandards.pdf〕 Some of these standards are: *The use of ISO 16067-1 and ISO 16067-2 standards for resolution requirements. *Recommended 400 ppi resolution for OCR'ed printed text. *The use of 24-bit color when color is an important attribute of a document. *The use of the scanning device's maximum resolution for digitally reproducing photographs *TIFF as the standard file format. *Attachment of descriptive, structural, and technical metadata to all digitized documents.
