Digital Libraries

We seek to aid designers of digital library interfaces and web sites in creating comprehensible, predictable and controllable environments for their users.  Our work on interactive exploration of digital materials goes back to the early research on Hypertext in 1983 with the development of HyperTies. In our more recent projects we promote visual previews and overviews to allow users to rapidly discriminate objects of interest from those not of interest, and to more fully understand the scope and nature of a digital library.

Emily Dickinson's Correspondences: A Born-Digital Textual Inquiry Screenshot

Emily Dickinson's Correspondences: A Born-Digital Textual Inquiry
This XML-based archive brings together seventy-four poems and letters from Emily Dickinsonís correspondence with her sister-in-law and primary confidante, Susan Dickinson. Each text is presented with a digitized scan of the holograph manuscript. These images have zoom functionality as well as a special light-box feature that allows users to view and compare constellations of related documents. Users may search by date, genre, manuscript features, and full text. Dating from the 1850s to the end of Dickinsonís life, the work collected here shows all the characteristics of the poetís mature art.
