The paper needs to be thin (Japanese tissue paper was much used in copy
books) and the ink needs to be hygroscopic, if a good copy was expected.
A typical iron gall ink (tannic acid, ferrous sulfate, gum arabic, and
water) could be made into a copying ink by adding either grape sugar,
glycerine, dextrine, calcium chloride, etc.
Most every historical society and many public libraries will have one or
more old copy/letter books to look at.
