I'm a non-chemist attempting to put together a chemistry paper. Up to now I've got my thermodynamic data from various random pdf files found on the web, together with Wikipedia. Now that the paper is nearly finished I need to replace these with values from a single, respectable source. But I've realised I don't know how to find such a source. I have a few chemistry textbooks on my desk, which tend to have tables in the back, but they're not terribly comprehensive and none of them have all the data I need.
So is there a standard resource for thermodynamic tables? I particularly need the Gibbs energy and enthalpies of formation for gases found in the atmosphere, such as $\ce{O2}$, $\ce{CO2}$, $\ce{CH4}$ and $\ce{H2O(vapour)}$? In an ideal world this would either be something I can access online or a book that's likely to be found in my institute's rather small library.
