If you have the storage space on CD or otherwise, yes.  If not, it is not
necessary - scan in 16 bit, do perhaps basic corrections, convert to 8-bit
and save.  I would save them at 1200dpi if possible, though.

I would suggest scanning and saving them in color, especially since you
mention below that the old paper is not showing a color cast.  You may well
find that one or more of the channels have better detail, contrast,
luminosity etc. than others.  See Chapter 13 of Dan Margulis's Professional
Photoshop 5 or 6.  See

| What about color prints that need strong color correction? In Poland
during

| prints have a very strong reddish color cast now. Auto Adjust helps a lot

Stretch them from 0 to 255 for purposes of saving to disk.
