I have a very old deed original (1849) that looks like a torn up copy of the declaration of independence. I would guess 85% of it is still legible and restorable, but it does have some tears and gaping holes in parts of it.

1) How do I get it scanned in? It's large - about 16x16, and obviously won't fit on my flatbed scanner.

2) How do I preserve it, physically, so it won't become further damaged?

Thanks!
