# Long description

A block graph demonstrating the increasing volume of cultural heritage policy documents from the 1870s to the 1990s. One is recorded in the first decade; none in the 1880s and 1890s; one in the first decade of the twentieth century (1900–1909); no more until the 1930s when four policy documents are noted; none in the 1940s; in the fifties a return to the level of the thirties; and a steady rise to 7 in the sixties, 12 in the seventies, 13 in the eighties; then a huge rise to 34 in the nineties.
