 What sort of georeferencing do you mean? Imagery? Or getting coords
from text (placenames etc)?

 I'd use Quantum GIS for georeferencing imagery - the georeferencing
plugin there lets you load in an image, click points on the image and
either enter coordinates or click the corresponding point on a visible
map. Then click the 'go' button and it works out the transform to
overlay your image on the map correctly.

  For text referencing you might be able to use my "geonames" R
package to search location info from the www.geonames.org database.
