A demonstration of American Memory by its coordinator, Carl FLEISCHHAUER,
and Ricky ERWAY, associate coordinator, Library of Congress, concluded
the morning session. Beginning with a collection of broadsides from the
Continental Congress and the Constitutional Convention, the only text
collection in a presentable form at the time of the Workshop, FLEISCHHAUER
highlighted several of the problems with which AM is still wrestling.
(In its final form, the disk will contain two collections, not only the
broadsides but also the full text with illustrations of a set of
approximately 300 African-American pamphlets from the period 1870 to 1910.)
As FREEMAN had explained earlier, AM has attempted to use a small amount
of interpretation to introduce collections. In the present case, the
contractor, a company named Quick Source, in Silver Spring, MD., used
software called Toolbook and put together a modestly interactive
introduction to the collection. Like the two preceding speakers,
FLEISCHHAUER argued that the real asset was the underlying collection.
FLEISCHHAUER proceeded to describe various search and retrieval
capabilities while ERWAY worked the computer. In this particular package
the "go to" pull-down allowed the user in effect to jump out of Toolbook,
where the interactive program was located, and enter the third-party
software used by AM for this text collection, which is called Personal
Librarian. This was the Windows version of Personal Librarian, a
software application put together by a company in Rockville, Md.
Since the broadsides came from the Revolutionary War period, a search was
conducted using the words British or war, with the default operator reset
as or. FLEISCHHAUER demonstrated both automatic stemming (which finds
other forms of the same root) and a truncated search. One of Personal
Librarian's strongest features, the relevance ranking, was represented by
a chart that indicated how often words being sought appeared in
documents, with the one receiving the most "hits" obtaining the highest
score. The "hit list" that is supplied takes the relevance ranking into
account, making the first hit, in effect, the one the software has
selected as the most relevant example.
While in the text of one of the broadside documents, FLEISCHHAUER
remarked AM's attempt to find ways to connect cataloging to the texts,
which it does in different ways in different manifestations. In the case
shown, the cataloging was pasted on: AM took MARC records that were
written as on-line records right into one of the Library's mainframe
retrieval programs, pulled them out, and handed them off to the contractor,
who massaged them somewhat to display them in the manner shown. One of
AM's questions is, Does the cataloguing normally performed in the mainframe
work in this context, or had AM ought to think through adjustments?
