  1. Digital Libraries Lillian N. Cassel Fall 2009

  2. A digital library • An informal definition of a digital library is a managed collection of information, with associated services, where the information is stored in digital formats and accessible over a network. -- • William Arms, Digital Libraries, 1999 • A focused collection of digital objects, including text, video, and audio, along with methods for access and retrieval, and for selection, organization, and maintenance of the collection. -- • Witten and Bainbridge, How to Build a Digital Library 2003

  3. Overview of this course • This course is about presentation of information on the Web, with special attention to Digital Libraries. • Required coursework will include • Readings, discussion (in class and online), and projects. There will be no examinations, unless circumstances indicate a need for one. • Class web page and WebCT/Blackboard

  4. Goals for Class 1 • Introduce the concept of a digital library • Introductions: Who are we and what do we want to achieve in this class? • Review the course structure • Look at WebCT • Describe assignments, projects to be expected • Look at the calendar • Introduce some tools – Concept maps • Make sure we know what a traditional library is! • Introduce the 5 S model for digital libraries

  5. Some tools - concept maps • Concept Maps • A graphical representation of concepts, ideas, topics, entities and relationships among them. • A useful tool: cmap from IHMC • See http://cmap.ihmc.us/ • Explore the cmap page, including a concept map about concept maps • Do a pencil & paper concept map on a subject of interest to your group -- a sport, a season of the year, a career interest, whatever. Use at least 20 nodes. We will look at a selection of these and offer suggestions.

  6. What is a library? • An active exercise to explore what we know about, and think about, traditional libraries. • How do we translate these characteristics to the digital world? • Is that the right model? Are we unnecessarily constraining the digital environment? Are there things that do not translate?

  7. The 5 S model • There are many details to digital libraries • The 5S model gives us a base to work from in creating a new DL • The 5S model is the work of Edward A. Fox and his students at Virginia Tech. These slides rely heavily on that work.

  8. The 5S model • Streams • The flow of information in various formats • Structures • Organizational aspects of the DL • Spaces • Views of components; real or abstract images • Scenarios • Services and behaviors • Societies • Communities and relationships among them

  9. 5S Summary Source: http://www.dlib.vt.edu/projects/5S-Model/

  10. Some examples • The Etana project • Nice because the things that are “in” the digital library are real (not digital) objects • CITIDEL and computingportal • These are projects with local involvement • You may want to connect to these

  11. Etana - A DL for archeology

  13. CITIDEL • The Computing and Information Technology Interactive Digital Education Library • Located at Villanova • Built in DSpace • www.citidel.org

  14. Ensemble • ComputingPortal.org • A larger example of what a digital library can be. • A real community center • Upcoming events, things to share, meeting places • Underlying repository is fedora • Front end through Drupal

  15. Class 1 summary • Course plan described and discussed • Class members surveyed • Tools – concept maps -- introduced • Concept mapping practiced • The idea of a library, and of a digital library, explored. • The 5S model introduced • Some example digital libraries explored

  16. Next week: • Check the calendar • Readings and an assignment due • The 5 S model for digital libraries (and other information retrieval systems) continued • .Always check the calendar. I will update that as things change
