Books by Matthew Hayes

Beginning in the 1950s, alleged UFO sightings sparked tension between the Canadian government and its citizens. The public demanded investigation and disclosure while the state appeared unconcerned. In Search for the Unknown Matthew Hayes presents the first comprehensive history of UFO investigations in Canada.

Repairing works of art and writing about them-the practices that became art conservation and art history-share a common ancestry. This handsomely illustrated volume charts the intersections between the two fields in the treatment of Italian Renaissance paintings in nineteenth-century Europe and proposes a model for a new conservation history.
