Preservation
Dittoed copies now pose a serious challenge to archivists responsible for historic document and artistic preservation. Dittoed images would gradually fade with exposure to ultraviolet light, limiting their usability for permanent labels and signage. When exposed to direct sunlight, ditto copies could fade to illegibility in less than a month. The low-quality paper often used would yellow and degrade due to residual acid in the untreated pulp. In the worst case, old copies can literally crumble into small particles when handled.

Famous quotes containing the word preservation:
“It is my hope to be able to prove that television is the greatest step forward we have yet made in the preservation of humanity. It will make of this Earth the paradise we have all envisioned, but have never seen.”
—Joseph O’Donnell. Clifford Sanforth. Professor James Houghland, Murder by Television, just before he demonstrates his new television device (1935)
“The bourgeois treasures nothing more highly than the self.... And so at the cost of intensity he achieves his own preservation and security. His harvest is a quiet mind which he prefers to being possessed by God, as he prefers comfort to pleasure, convenience to liberty, and a pleasant temperature to that deathly inner consuming fire.”
—Hermann Hesse (1877–1962)
“The preservation of life seems to be rather a slogan than a genuine goal of the anti-abortion forces; what they want is control. Control over behavior: power over women. Women in the anti-choice movement want to share in male power over women, and do so by denying their own womanhood, their own rights and responsibilities.”
—Ursula K. Le Guin (b. 1929)
