This is my workflow for turning paper into PDF documents. I make no claim that it is efficient, nor that it will work for anybody else...
1) Can I find this online? More than half the contents of my tab binder originally came from online sources. If I can't download the file directly as a PDF, I take a screen capture, clean it up in Paint, and export as PDF. Does this take less time than scanning the page? Hmm... probably not. But it's more fun.
2) Do I need this song? You know how when you're packing to move, you find clothes in the closet that you would have kept for years except now that you're moving you'd rather get rid of them? It's easy to accumulate tab you'll never play, but that doesn't mean you have to scan it.
3) Relocate the printer/scanner/copier so it's sitting on my desk, not tucked behind another printer on a side table. Now it's convenient to scan a few pages while I check email and drink coffee. My scanner takes about a minute to scan a page at 300 dpi. Black and white scans are faster than color, so check your settings. I'm using a Canon MP470 flatbed which is surely obsolete by now.
4) Knuckle down and spend a few rainy afternoons scanning. At least it's better than cleaning house (and, unlike a clean house, once paper's scanned it stays scanned).
I've been scanning photo albums (pre-digital) and it's going faster than I expected. A friend tells me she scans photos while watching TV. If your tab is in good enough shape to pass through a sheet feeder, maybe check out the scanning services at FedEx/Kinko's or Staples. Or bribe someone. Teenagers might be talked into a few hours of scanning for babysitting-rate pay.
Now if I can just get started converting all these VHS tapes to DVD...
