Software repositories have traditionally provided access to software resources for particular communities of users within specific domains. For example, our Netlib gif [6] and GAMS gif [4] repositories provide access to collections of mathematical software, while our National HPCC Software Exchange (NHSE) gif [5] provides access to high performance computing resources. The growth of the World Wide Web has created new opportunities for expanding the scope of discipline-oriented repositories, for reaching a wider community of users, and for expanding the types of services offered. Reaching a wider community of users has created a need for increased automated assistance in locating appropriate resources and in understanding and making use of these resources.

The goal of our software repository research is to improve access to tools for doing computational science for both expert and non-expert users. We are exploring the use of emerging Web and network technologies for enhancing repository usability and interactivity. Technologies such as Java, Inferno/Limbo, and remote execution services can interactively assist users in searching for, selecting, and using scientific software and computational tools. This paper describes various related prototype experimental interfaces and services we have developed for traversing a software classification hierarchy, for selection of software and test problems, and for remote execution of library software. After developing and testing our research prototypes, we deploy them in working network services useful to the computational science community.

Although the focus of our work has been on software repositories, we believe that many of the results are applicable to other types of digital libraries, especially with respect to the provision of interactive and dynamically generated content.
