Revision History

Revision History

A generative software application that autonomously downloads and composites images from the American Memory Collections Database with various raster effects.

The National Digital Library Program is an effort to digitize and deliver electronically the distinctive, historical Americana holdings at the Library of Congress. The American Memory Historical Collections, major component of the Library’s National Digital Library Program, are multimedia collections of digitized documents, photographs, recorded sound, moving pictures, and text from the Library’s Americana collections. There are currently 80 collections containing over one million documents in the American Memory Digital Library.

By tapping into the Library’s Digital Americana assets, the Revision History software enables users to observe as these historical documents are endlessly juxtaposed and decimated. These “revised” historical images can then be saved to the user’s storage disk and publicly shown.


The software was written with Max/NATO.0+55 for MacOS 9 and was publicly available for download through three versions, and finally made obsolete in 2005. Future update to MacOS X is under consideration.  A full print collection  of thousands collages is available for exhibition and/or sale.
