The choice of a given database as source of auxiliary values may not be straightforward, even for a thermochemist. Consistency is a very important criterion, but factors such as the publication year, the assignment of an uncertainty to each value, and even the scientific reputation of the authors or the origin of the database matter. For instance, it would not be sensible to use the old NBS Circular 500 [22] when the NBS Tables of Chemical Thermodynamic Properties [17], published in 1982, is available. If we need a value for the standard enthalpy of formation of an organic compound, such as ethanol, we will probably prefer Pedley s Thermodynamic Data and Structures of Organic Compounds [15], published in 1994, which reports the error bars. Finally, if we are looking for the standard enthalpy of formation of any particular substance, we should first check whether it is included in CODATA Key Values for Thermodynamics [16] or in the very recent Active Thermochemical Tables [23,24],... 

The standard enthalpies of formation of all the reactants and products of reaction 2.21 can be found in the NBS Tables of Chemical Thermodynamic Properties [17] Af77°(C2H5OH 60H2O, sin) = -287.72 kJ mol-1,...

For the diligent reader, thermochemical conventions are well-discussed in D. D. Wagman, W. H. Evans, V. B. Parker, R. H. Schumm, I. Halow, S. M. Bailey, K. L. Churney and R. L. Nuttall, The NBS Tables of Chemical Thermodynamic Properties Selected Valuesfor Inorganic and C, and C2 Organic Substances in SI Units , J. Phys. Chem. Ref. Data, 11 (1982), Supplement 2. However, the various subtleties expressed in this source, such as the above-cited ambiguities in temperature and pressure, have but negligible effect on any of the conclusions about cyclopropane and its derivatives in this chapter the data are too inexact and the concepts we employ are simply too sloppy to be affected.

These methods were used in this work when necessary. However, in many cases the equilibrium constants could be calculated by a computer program developed by Outukompu Research, which uses data stored in their program. These data are usually the most recent available. References used in this program are listed below. When data above 298 K were not available, data at 298 K are given. These are taken from Wagman, D. D. Evans, W. H. Parker, V. B. Schumm, R. H. Halow, I. Bailey, S. M. Chumey, K. L. and Nuttall, R. L., The NBS tables of chemical thermodynamic properties, J. Phys. Chem.
