Abstract
Abstract Translucent plastic pages of an improved design for the filing of color film slides, wherein the storage trays are slightly indented to remove the slide emulsion from direct contact with the plastic. In accordance with a further feature, the translucent storage pages are formed from archival material, and are designed alternatively to be suspended in a file cabinet by means of a hanging bar which affixes to the page, and includes an indexing tab; or to be stored in a conventional ring binder, without the hanging bar.
