Why scan first? We discussed this at the USNP meetings--microfilm first then scan from film. You lose so much data in the translation to digital.According to Tanya Brun: . . We have started a project here at Brandeis scanning papers from the Andrei . Sakharov Archives. The materials in the archives consist of typescript, . manuscripts, and some photos. We are scanning at 400 dpi resolution in . grayscale primarily, with some materials in color. We are using 400 dpi . resolution with the intent that microfilm can be produced from the . digitized images in the future. . We are interested in hearing from others whether 400 dpi 8-bit grayscale . and color images are considered sufficient for this purpose, or whether we . should increase our scan resolution to say 600 dpi grayscale and true color . for preservation-quality microfilm. Any recommendation will be appreciated. . . Tanya Brun . Archive Assistant . The Andrei Sakharov Archives . Goldfarb Library . Brandeis University .
