This paper presents a library of reusable model components for visual simulation of the Networked Computer Science Technical Report Library (NCSTRL) and illustrates how a visual simulation model can be developed for a new NCSTRL configuration by way of component reuse with no programming. Such a repository of reusable model components can be created for visual simulation of any digital library for the purpose of performance evaluation and tuning and conducting what-if analyses for different system design configurations.
