1. A method for document internal localization comprising: identifying, for a multiplicity of regions of an electronically stored document, if there are regions which are indistinguishable, by an automated processing component, from other regions in the multiplicity of regions; in the event that regions which are indistinguishable are identified, for a set of regions which are indistinguishable from each other, adding machine readable disambiguating information to at least one of the regions in the set whereby the regions in the set of regions are distinguishable by the automated processing component; associating each of the regions in the multiplicity of regions with a corresponding location in the electronic document; generating a hardcopy document from the electronic document; comparing an observed region of the hardcopy document with a first region in the multiplicity of regions with the automated processing component and, where the observed region of hardcopy document is indistinguishable from the first region, retrieving the location associated with the first region.
