Reusability is an important concept in software development because it provides many benefits, including shorter development cycles, increased software reliability and lower production costs. This paper describes the experiences of developing a portal of reusable components to support information retrieval teaching and research in a Master’s programme in information studies at Nanyang Technological University in Singapore. The portal contains the source code of these components and covers a variety of areas in the field of information retrieval such as algorithms and data structures for lexical analysis, indexing and ranking. The portal provides users with features to search or browse for code, contribute new code under appropriate categories, participate in threaded discussions and rate source code. The portal also contains document management features that allow co‐ordinators to evaluate contributions before publishing them for general access.
