UNIVERSITY OF MICHIGAN OFFERS FREE ACCESS TO DIGITAL
LIBRARY SOFTWARE
One week after a University of Michigan (UM) report that
suggested the school help "the world grapple with an
explosion of information," the university library is making
good on the suggestion. The U. of Michigan library
announced last week that it will offer free access to a
suite of "class-based middleware" software designed to
facilitate communication between the web and digital
library tools such as a search engine. According to library
spokersperson Wanda Monroe, the software tools, created by
developers at the university library, provide "an easy,
consistent method for supporting online collections."
In addition, to facilitate the further development and to
assist the information community in building and deploying
electronic resources, the UM library will provide free Open
Source access to these tools, inviting users to modify and
adapt the classes and to share the innovations with the
broader community "in the spirit of the Open Source
Initiative." To learn more about UM's class-based software
and related products, go to
