Carl FLEISCHHAUER, coordinator, American Memory, Library of Congress,
emphasized that he would attempt to represent the people who perform some
of the work of converting or preparing materials and that the core of
the Workshop had to do with preparation and production. FLEISCHHAUER
then drew a distinction between the long term, when many things would be
available and connected in the ways that GIFFORD described, and the short
term, in which AM not only has wrestled with the issue of what is the
best course to pursue but also has faced a variety of technical
challenges.
FLEISCHHAUER remarked AM's endeavors to deal with a wide range of library
formats, such as motion picture collections, sound-recording collections,
and pictorial collections of various sorts, especially collections of
photographs. In the course of these efforts, AM kept coming back to
textual materials--manuscripts or rare printed matter, bound materials,
etc. Text posed the greatest conversion challenge of all. Thus, the
genesis of the Workshop, which reflects the problems faced by AM. These
problems include physical problems. For example, those in the library
and archive business deal with collections made up of fragile and rare
manuscript items, bound materials, especially the notoriously brittle
bound materials of the late nineteenth century. These are precious
cultural artifacts, however, as well as interesting sources of
information, and LC desires to retain and conserve them. AM needs to
handle things without damaging them. Guillotining a book to run it
through a sheet feeder must be avoided at all costs.
Beyond physical problems, issues pertaining to quality arose. For
example, the desire to provide users with a searchable text is affected
by the question of acceptable level of accuracy. One hundred percent
accuracy is tremendously expensive. On the other hand, the output of
optical character recognition (OCR) can be tremendously inaccurate.
Although AM has attempted to find a middle ground, uncertainty persists
as to whether or not it has discovered the right solution.
Questions of quality arose concerning images as well. FLEISCHHAUER
contrasted the extremely high level of quality of the digital images in
the Cornell Xerox Project with AM's efforts to provide a browse-quality
or access-quality image, as opposed to an archival or preservation image.
FLEISCHHAUER therefore welcomed the opportunity to compare notes.
FLEISCHHAUER observed in passing that conversations he had had about
networks have begun to signal that for various forms of media a
determination may be made that there is a browse-quality item, or a
distribution-and-access-quality item that may coexist in some systems
with a higher quality archival item that would be inconvenient to send
through the network because of its size. FLEISCHHAUER referred, of
course, to images more than to searchable text.
