Item Bringing Treasures to the Surface - Iterative Design for the Library of Congress National Digital Library Program(1998-10-15) Plaisant, Catherine; Marchionini, Gary; Bruns, Tom; Komlodi, Anita; Campbell, LauraThe Human-Computer Interaction Lab worked with a team of the Library of Congress (LC) to develop and test interface designs for LCUs National Digital Library Program. Three iterations are described and illustrate the progression of the design toward a compact design that minimizes scrolling and jumping and anchors users in a screen space that tightly couples search and results. Issues and resolutions are discussed for each iteration and reflect the challenges of incomplete metadata, data visualization, and the rapidly changing web environment.Item Interfaces and Tools for the Library of Congress National Digital Library(1998-10-15) Marchionini, Gary; Plaisant, Catherine; Komlodi, AnitaThis paper describes a collaborative effort to explore user needs in a digital library, develop interface prototypes for a digital library, and suggest and prototype tools for digital librarians and users at the Library of Congress (LC). Interfaces were guided by an assessment of user needs and aimed to maximize interaction with primary resources and support both browsing and analytical search strategies. Tools to aid users and librarians in overviewing collections, previewing objects, and gatherin g results were created and serve as the beginnings of a digital librarian toolkit. The design process and results are described and suggestions for future work are offered.

This assessment provides an informed basis for the interface design and evaluation to be done in the months to come. It was prepared under the Librarys contract with the Human-Computer Interaction Laboratory (HCIL) at the University of Marylands to work together to design an interface for the Librarys National Digital Library (NDL) Program. In order to determine user needs, HCIL conducted a survey of nine reading rooms with special emphasis on the Special Collections from which the content of the NDL will be drawn. HCIL also used questionnaires to reach remote audiences who may typify NDL users accessing the Library via the Internet. They also analyzed many of the documents available in the Reading Rooms, such as finding aids, other handouts, and user studies.Item Visualizing websites using a hierarchical table of contents browser: WebTOC(1998-11-20) Nation, David A.; Plaisant, Catherine; Marchionini, Gary; Komlodi, AnitaA method is described for visualizing the contents of a Web site with a hierarchical table of contents using a Java program and applet called WebTOC. The automatically generated expand/contract table of contents provides graphical information indicating the number of elements in branches of the hierarchy as well as individual and cumulative sizes. Color can be used to represent another attribute such as file type and provide a rich overview of the site for users and managers of the site. Early results from user studies suggest that WebTOC is easily learned and can assist users in navigating websites. (Also cross-referenced as UMIACS-TR-97-41)
