David,
The other option is to microfilm the sheet music and scan the
microfilm. This will produce a very high quality film copy that will be
preserved (life expectancy of properly produced and stored microfilm is 500
years)
The microfilm frame can then be scanned either in binary or
grayscale. This is what we (Preservation Resources) are doing for the
Library of Congress. We are digitizing printed Music placed on copyright
deposit with the Library from 1870-1885 as part of the National Digital
Library Program. The sheet music collection has not been posted yet to the
LC site (http://memory.loc.gov/). You will probably need to produce a
monitor-sized derivative image for viewing/browsing.
The most important elements in filming and scanning will be to
dealing with faded and damaged material, creating good contrast between
paper (high contrast microfilm will actually help with this) and print and
capturing fine details such as dotted notes, thirty-secondths notes. We are
scanning the sheet music at 400 dpi and rescanning and integrating selected
graphics at 200 dpi, 8-bit.
