When Don Swanson hypothesized a connection between Raynaud's phenomenon anddietary?shoil, the?eldofliterature-baseddiscovery(LBD)wasborn. During thesubsequenttwodecadesasteadystreamofresearchershavepublishedarticles aboutLBDandthe?eldhasmadesteadyprogressinlayingfoundationsandc- ating an identity. It is curiously signi?cant that LBD is not "owned" by any p- ticulardiscipline, forexample, knowledge discoveryortextmining. Rather, LBD researchersoriginatefromarangeof?eldsincludinginformationscience, infor- tionretrieval, logic, andthebiomedicalsciences.
