Reviews information with respect to inhibitors of metal corrosion, which is thought to be relevant to museum curators, restorers and collectors. Inhibitors of inorganic nature are mentioned, while organic inhibitors, because of their multiplicity and importance, are dealt with extensively. Special attention is given to the vapour phase inhibitors, and their use in closed spaces, such as glass-cases and depots. The health hazards involved in working with those chemicals are also discussed.
