We present new measurements of the 7Be(p,γ)8B cross section from E¯cm=116 to 2460 keV. Our new measurements lead to S17(0)=22.1±0.6(expt)±0.6(theor)eV  b based on data from E¯cm=116 to 362 keV, where the central value is based on the theory of Descouvemont and Baye. We compare our results to other S17(0) values extracted from both direct (7Be(p,γ)8B) and indirect (Coulomb dissociation and heavy-ion reaction) measurements, and show that the results of these 3 types of experiments are not mutually compatible. We recommend a “best” value, S17(0)=21.4±0.5(expt)±0.6(theor)eV  b, based on the mean of all modern direct measurements below the 1+ resonance.
