OCR is of limited usefulness when graphics need to
accompany the text.

Cecil:

Very true, however, the graphics in question can be copied (such as with
your method), clipped, saved as an individual image (away from any
"text") and added/inserted to the text gleaned from using the OCR
program, allowing one to "recreate" the original document(s).

Not easy (or for the faint hearted), but can be done ...
