The Conversion Process
The materials in the MOA collection are scanned from the original paper
source, with materials disbound locally due to the brittle nature of many
of the items. The conversion of the materials has been outsourced to
Northern Micrographics, Inc., a service vendor in LaCrosse, WI. The
images are captured at 600 dpi in TIFF image format and compressed using
CCITT Group 4. Minimal document structuring occurs at the point of
conversion, primarily linking image numbers to pagination and tagging
self-referencing portions of the text. In the case of serials, low-level
indexing will be added post-conversion by the partner institutions;
Cornell and Michigan staff are collaborating to determine low-level
indexing guidelines for this complex group of serial titles.
Further conversion of the University of Michigan materials (approximately
685,000 pages from within the total project) includes both optical character
recognition of the page images, and SGML-encoding of the ensuing textual
information. For more information, please consult information
