Yes, I recommend scanning at a higher resolution (even 150 dpi can be a good
starting point). This will result in a very large image on your monitor.
Then resize the image (at 72dpi) for a maximum width of 640 pixels (the
width of your SVGA monitor screen) .
Then apply an "unsharp" mask. Every image editor has one, though it may
have a slightly different name (ie sharpen or sharpen lite).

> I'll second that. Think of scanning at a much higher DPI as obtaining
more information, which can then be reduced in an "average" fashion
("muting" noise in the original scan, too). And don't be afraid to play
around -- the first scan is rarely the optimal one. One caveat: don't scan
any higher than the highest *mechanical* resolution, or the software in the
scanner will simply perform interpolations, defeating much (though not all)
of the value of the higher-DPI scan.
