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
