ABSTRACT
Scientists need new tools to explore and browse large collections of scholarly literature. Thanks to organizations such as JSTOR, which scan and index the original bound archives of many journals, modern scientists can search digital libraries spanning hundreds of years. A scientist, suddenly faced with access to millions of articles in her field, is not satisfied with simple search. Effectively using such collections requires interacting with them in a more structured way: finding articles similar to those of interest, and exploring the collection through the underlying topics that run through it.
