Integrating Libraries and
Electronic Publishing
The DART Project at Columbia
University
Ann Miller, David Millman, and Kate Wittenberg
Educational Mission
• To help undergraduate students gain
insight into the ways in which
anthropologists conduct research and
draw conclusions
• To improve information literacy of
undergraduate anthropology students
through use of structured yet unfiltered
digital resources
Wittenberg/Millman—2005 April—#2
E-Publishing Mission
• To develop a digital library infrastructure
that will store digital resources so that they
can be used in flexible ways
• To catalogue digital assets embedded
within complex learning tools so that they
can be used for broader research and/or
teaching goals
Wittenberg/Millman—2005 April—#3
Case 1:The Ethnographic
Imagination
• Modules present digitized selections from
ethnographer’s field notes, published work,
video interview
• Students interpret a village census; explore
stages of observation; compare ethnographers’
conclusions
• Assignments include writing about path from
field data to ethnography
• Focus is on increasing students’ grasp of how
anthropological knowledge is created
Wittenberg/Millman—2005 April—#4
Case 2: Intro to South Asian
Culture
• Online syllabus that links to catalogued
digital assets (primary texts, maps, photos,
video)
• Teacher builds class assignments around
these assets (response to specific
questions, essays on readings, and full
research paper)
• Increasing levels of interaction with library
materials throughout the semester
Wittenberg/Millman—2005 April—#5
Digital Teaching Tools and
Research Library Resources
• Focus on the relationship between the
“closed” world of the classroom and
teaching tools, and the “open” world of the
Web
• Can students explore freely the vast array
of research tools available through the
Web, while still having an appropriate level
of guidance concerning how to select and
evaluate the sources that they find?
Wittenberg/Millman—2005 April—#6
Unlimited Information as Benefit or
Obstacle to Learning
• How do we make information meaningful
to users with diverse skills and needs?
• Future work will explore how to find the
right balance between directed and
unfiltered presentation of digital teaching
and research materials in electronic
publications
Wittenberg/Millman—2005 April—#7
Technology
• Accommodate different styles for teaching
– fall ’04 (South Asian History & Culture): web browser
focus (syllabus navigation)
– spring ’05 (Ethnographic Imagination): digital
resource focus (primary source navigation)
– fall ’05 (planning): considering mobile device in DL
discovery & retrieval
• Web services import/export
• Access management
• Metadata: “versions” revisited

Access Management
• bi-lateral Shibboleth “federation” with LSE
• technology ok, though evolving
• federation scalability challenges
– process documentation
– policy
– legal
Wittenberg/Millman—2005 April—#18
Mobile
• front-end assumptions
• back-end assumptions
Wittenberg/Millman—2005 April—#19
Versions
• Lots of metadata moving around
• Identifiers back in the forefront?
• Evolution of OAI-PMH ?

Next Steps
• Export to local course management
system (pilot Sakai-based)
• Experiment with non-html tools for content
viewing / navigation
• Wider discussion of versioning issues
