Map conservation project at Trinity College Library Dublin

TLDR: In this paper, the first edition of the six-inches-to-one-mile Ordnance Survey maps of Ireland were conserved by encapsulating them in Melinex polyester film.

Abstract: This paper describes the conservation of the first edition of the six-inches-to-one-mile Ordnance Survey maps of Ireland. It outlines the general problem of the acidity of paper on which nineteenth-century Ordnance Survey maps are printed and the peculiar problems of conserving a hand-coloured presentation set. Each stage in the process is described up to the final encapsulation of the maps in Melinex polyester film.
