Insights (so far) Cultural & knowledge differences

Scientists unfamiliar with bibliographic standards and conventions

Librarians unfamiliar with NSF/NSDL environment Librarians learning new XML/OAI applications Ambiguous meanings of “library” & “cataloging”

XML Harvester collects & converts metadata Cataloging digital objects is both different &

the same as cataloging traditional resources
