What would be the minimums in resolution and
color/gray scale retainment required for a "paperless office"? Minimums
as to agency requirements, IRS and others. Several times I tried to find
official guidelines but there wasn't much. It would be nice if at least
some stuff could go electronic.

I've got about half my articles digitized.

For monochrome 1-bit images, I've found 300 dots-per-inch is
fine--as good as an excellent fax--*except* you'll lose the occasional
subscript, superscript, or fine-print. Those items become too
pixellated to read at that resolution. 600 dpi binary images are
great, tiny details are clear.

100dpi 8-bit grayscale is surprisingly readable, and is what I've
stored some older magazine articles with photos in, but that's max'd
out: 'zooming' in reveals no further detail. It's much nicer to use
200+ dpi in grayscale, and then be able to zoom in and see details
clearly when things aren't so clear.

Optical character recognition (OCR): many programs work MUCH better
with 600dpi 1-bit images (e.g. Pagis Pro), though my ancient version of
PaperPort likes 300dpi fine, and recognizes more accurately than its
(former) competitor with 4x the pixels.
