We argue that the resource shar- ing that is commonly manifest in semantic accounts of coordination is instead appropriately handled in terms of structure-sharing in LFG f-structures. We provide an extension to the previous account of LFG seman- tics (Dalrymple et al. , 1993a) accord- ing to which dependencies between f-structures are viewed as resources; as a result a one-to-one correspon- dence between uses of f-structures and meanings is maintained. The result- ing system is sufficiently restricted in cases where other approaches overgen- erate; the very property of resource- sensitivity for which resource sharing appears to be problematic actually provides explanatory advantages over systems that more freely replicate re- sources during derivation.
