Manuscripts of Colonial and Revolutionary America

Notes on the Images

To create the images used here, manuscript materials were originally scanned in full color at 300 DPI and saved as compressed TIFF image files. These color images were then archived on CD. Earlier materials were scanned on a UMAX Mirage II flatbed scanner (2001-2005); materials are currently scanned on one of two Microtek ScanMaker 9800XL scanners. All images are acquired and archived using Macintosh computers.

From the archived color images, the online black and white JPEG files were created at 150, 100 and 72 DPI. These images were, as necessary, digitally manipulated a minimal amount to increase the contrast between the words and the page on which they are written, and thus increase the legibility of the text.
