A compendium of phase change enthalpies published within the period 1880–2010 is reported. Phase change enthalpies including fusion,vaporization, and sublimation are included for organic, organometallic,and a few inorganic compounds. This compendium is a combination of three previous series focusing on phase change enthalpies updated to 2009. Sufficient data are presently available for some compounds to permit thermodynamic cycles to be constructed, an important manner of evaluating the reliability of the measurements. Temperature adjustments of phase change enthalpies from the temperature of measurement to the standard reference temperature, T=298.15 K, are briefly discussed and a protocol for doing so is illustrated.
