A paper and its immediate references are displayed on a single webpage. Unfortunately, it is not readily apparent where the paper belongs in the greater context of a research field. Our goal was to develop, test, and iteratively improve the effectiveness of a web-based application, PaperCube, designed to augment and enhance a researcher's interaction with digital libraries through the use of interactive visualizations of bibliographic meta data. The visualizations set out to show different levels of detail and aspects of a paper's citation network. A primary concern was to ensure that while switching visualizations, the viewed paper or author remained focused at all times. PaperCube was validated through a user study that showed that it helped users who are trying to explore a field of research. In particular, PaperCube was shown to reduce the "cognitive load" put on a researcher and aid the "discoverability" of new research material.10aDigital libraries10aGraphical user interfaces10aNavigation10aPaperCube10aWeb-based visualization1 aBergström, P.1 aAtkinson, D.C.  uhttp://www.scopus.com/inward/record.url?eid=2-s2.0-79960682007&partnerID=40&md5=746cf2e1545b3dd8f0d1697f5673e6e8
