A set of The Atlantic Neptune dating from 1780 to 1781 and comprising 176 charts, views and title pages with many aquatints in monochrome and color was conserved. The leather binding had disintegrated, the boards were loose from the spine, the paper was highly acidic and soiled and there was considerable transfer of the printing inks to the opposite side of the folios creating ghost images. It was necessary to stabilize and buffer the paper to remove the ghost images through bleaching and to resew and rebind the volumes utilizing the original hard-marbled board paper.
