If something does come up a setup that allowed a DSLR (quite a few

This was the system used in a digital archive project that I was
involved in (letters, pamphlets, books, newspaper cuttings, handwritten
pages etc). The advantage is that the material can be any size (possibly
bigger than A2) if you use a camera and tripod with a laptop. And
speed: scanning several thousand objects on a scanner is not really
feasible. Watching this and then seeing the results, lighting is the
key. If you cover the object with glass or perspex to flatten it, then
reflection is a big problem. As I said, I watched this, rather carried
out the process.
But I worked on the restoration phase of the project (using Japanese
paper and a starch based glue for example). The archive is now in the
Bishopsgate Institute.
Examples of how it can be done (there are professional tripod and camera
setups as well).
