Utopia Library provides a mechanism for managing
collections of articles

of publishers' licenses). When a user opens a PDF fi le in Utopia, a small
semantic fi ngerprint is created that uniquely identifi es that paper to the
system. Any annotations or attachments are associated with this
fi ngerprint and not with the PDF fi le itself. This has signifi cant
consequences for sharing and copyright within corporate environments.

If a scientist on the other side of the world goes to the journal web site
and downloads a completely new PDF of a specifi c article, it has the same
fi ngerprint as any other copy of that article (even if the PDF is watermarked
by the digital delivery system to include provenance information). When
opened in Utopia, this fi ngerprint is recognized, and all enhancements
and company annotations are retrieved and overlaid on the article in real
time. This means that colleagues who may not even know that this paper
was of interest to someone in the company are able to exploit the tacit
knowledge of the organization that would otherwise be lost.
A corporate PDF repository is not required. When user A posts a paper
to the shared folder, user B sees the title, citation and so on, but does
not get a physical copy of the paper until they decide to read that
