Project Envision, an early attempt to build a digital library of Computer Science literature underlined the importance of the provision of "task-oriented access to electronic archives" as an important digital library principle (Fox et al, 1993). Specifically, the pre-development user study found that among the features desired in a new system was the "ability to do domain-oriented tasks" (such as embed code for testing, access to analytical tools, access to source code in a choice of languages). Other digital library projects such as CORE which attempted to build a chemist's workstation (Lesk, 1991) and Georgetown University's implementation of the Integrated Advanced Information Management System (IAIMS) which designed different kinds of workstations based on user groups such as scholars, practitioners, researcher, faculty, student (Broering, 1993) have implicitly recognized that both the nature of work and the subject domain are important factors in the design of digital libraries that support work. This research proposes to study the work of professionals in a subject domain as a prelude to the re-design of an existing print document into an electronic document that can be used in support of their work.
