We again credit follow collector Paul Sarna for providing the following information concerning the very beginning of microfilm as a means of allowing libraries to preserve valuable shelf space. It is excerpted from “News-Week” magazine of Oct. 28, 1933:
“…Another idea which got yet more attention was presented by Eastman Kodak Company. A new apparatus can photograph whole newspaper pages on a strip of film one and three-eights inches wide. An eight page paper would require a strip only twelve inches long, and a complete month’s file of a bulky metropolitan newspaper could be recorded on a four inch reel of film.
Any person wanting to find an item, for instance, in the Atlanta Constitution of July 15, would ask for the film of that date at the library desk. The film would then be snapped on an axle on top of a projection box. With the light switched on, a shadow, much like that cast by any motion picture projector, appears on a slanting screen before which the reader sits. A knob on the side of the apparatus moves the film rapidly until the desired page is reached.
One big advantage of the apparatus is that the items, thrown in clear relief, appear 50% larger than in newspapers. A year’s file, instead of occupying six feet of double shelving, would not take up much more room than a shoe box.
Furthermore the non-explosive film could be renewed an indefinite number of times and reprints of news items could be made by placing photosenstive paper on the projection screen.
The ingenious apparatus is largely the work of Roy S. Hopkins of the Eastman Research Laboratory…”.
An interesting review of the birth of microfilm. I would not have guessed it dated back to 1933.
Thanks Paul!
