Experiences with Developing a User-Centered Digital Library There are several studies which have followed the user-centred design process by conducting usability tests, surveys and more in order to elicit users' requirements from the users' point of view rather than from their own perspective. One of these is the Envision project, a study conducted by Fox et al. (1993), which interviewed users and experts in three areas: library, information and computer science. The aim of this project was to build a user-centred DL, by interviewing users about potential decisions on system functionality. The project focused on 12 participants who were professionals in the area of computer science and information retrieval. Participants were questioned on four topics: 1. 2. 3. current information retrieval practices current information dissemination practices desired information retrieval and manipula- tion capabilities RELATED WORKS Very interesting early work was conducted by Marchionini (1995), who initially focused on user-centred methods for library interface design. The suggestion was to have a working group which would involve participants from four types of users in libraries (Library staff; Frequent and Sophisticated users, who regularly use library services; Occasional users; and Potential users) who would work alongside the design team. Nev- ertheless, only one type of users of the working group usually works with the team at each stage of the design. For example, Frequent and Sophis- ticated users will be used for usability testing for an advanced version of the prototype design, while Occasional users will participate in verbal interviews or written questionnaires. Marchionini et al. (1998) also used the same approach and focused on user needs in a DL,
