Answers to clinical questions occurring during healthcare practitioner/patient interaction can be often found in National Library of Medicine's (NLM) databases. The recent advances in wireless handheld computers promise to make them a widely used tool to deliver needed information to the practitioner at the point of service. This paper addresses challenges in organizing and presenting information obtained from NLM's MEDLINE^® database of indexed citations in a way that wil helpractitioners reduce literature search time on handheld computers. We study two clustering algorithms and two methods of labeling document clusters.
