To: Multiple recipients of list IMAGELIB

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.
