scanners: herbarium specimen

[Steve at]

There are a number of herbaria imaging specimens, especially types.

A good place to start would be NYBG. See
http://www.nybg.org/bsci/herbarium_imaging/ for details of how they do
it.

Mobot also does extensive imaging.  See
http://www.mobot.org/MOBOT/Research/imaginglab/welcome.shtml for an
overview.

There's lots of information on this topic out there, the above two are
just a start.
