Many digital libraries are comprised of documents from disparate sources that are independent of the rest of the collection in which they reside. A userÕs ability to explore is severely curtailed when each document stands in isolation; there is no way to navigate to other, related, documents, or even to tell if such documents exist. We describe a method for automatically introducing topicÐbased links into documents to support browsing in digital libraries. Automatic keyphrase extraction is

Two implementations are described: one that applies these techniques to existing WWWÐbased digital library collections using standard HTML, and one that uses a wider range of interface techniques to provide more sophisticated linking capabilities. An evaluation shows that keyphraseÐbased similarity measures work as well as a popular full-text retrieval system for finding relevant destination documents.
