Scanning question

So, I have a bunch of old DEC Rainbow docs that aren't online. I also have a snapscan scanner that I use for bills and such. There's four kinds of docs, and I'm looking for advice: (1) wire-ring bounded. What's the best way to scan these? The easiest is to just clip the wire binding and drop it in the scanner. But then what? (2) Folded with staples. These are booklet format, with stables in the middle. I could easily remove the staple and scan. but how do I replace the staple? (3) Gum bound. These books are bound with some kind of gum / goo on the spine. Some of these are so old I could just remove it and have no real degradation of the state. Others have spines that are still in good shape. (4) Three ring binder. This is easy: remove, scan, replace. Right? Finally, how do I get the resulting scans into bigkeeper? Any fancy options I should enable to make the pdfs maximally useful? Warner
