The use of colour microfilm for preservation

In this article, the author discusses applications of microfilm, and history of its evolution, then introduces "Permanence of Color Microforms for Library Preservation Project". In continuation he offers the main results of the project as follows: 1) Color microfilming is a viable preservation method; 2) Cibachrome SBD films exibit superior permanence to chromogenic microfilms at room temperature and moderate RH conditions; 3) In the accelerated aging studies, films sealed in bags had a shorter life than films free hung in the chamber; and 4) The dark stability of Cibachrome dyes is far superior to chromatic dyes.
