This compendium summarizes the fusion enthalpies of approximately 1000 new measurements. A group additivity method developed to estimate the total phase change entropies and enthalpies of organic solids is updated, applied to the new data and the results are compared. The uncertainties associated with the 1016 new measurements, +/-18.5 J mol(-1) K-1 and 7.6 kJ mol(-1) for total phase change entropies and enthalpies, respectively, are similar in magnitude to those reported previously. Experimental and estimated fusion entropies and fusion enthalpies along with references are available as supplementary material. (C) 2009 Elsevier B.V. All rights reserved.
