I have been working for quite awhile with the treatment of experimental results in chemical thermodynamics. I have tried to organize my archives and make them available for others. There are several experimental datasets in computer readable format and I hope that they can be used as useful benchmarks for data fitting and nonlinear optimization. Experimental values have been collected from original research papers describing experimental results. All case studies are reasonably well documented in my papers. As such, the goal of the current document is to collect related information together.
