Collaborative project: a comprehensive heat of formation table?
Check out http://www.chemeo.com for a good starting point. It is an aggregation based on databases of high quality but less accessibility. The creator
values accuracy over breadth, so there are no anonymous contributions, but it is good inspiration for the sort of site you are envisioning.

Or just buy "SI Chemical Data" or the CRC handbook. I just don't see an amateur project producing valuable thermodynamic data.

The 89th edition (2008-09) of the CRC handbook is around $40 shipped and the 90th (2009-10) is around $70 shipped. I happened to come across a
high-quality .pdf of the 89th online. Chemeo is also nice as polverone mentioned.

Thanks for the links.
Of all those, I found Wolfram Alpha the most helpful. I guess there is no need to reinvent the wheel.
I'll delete my post.

My favorite source for this is The Thermochemistry of the Chemical Substances by F. Russell Bichowsky, Frederick D. Rossin (1951, 3rd
printing, 460 pages). It's a very handy book.
For a brief list of some heat of formation thermodynamics here. Just convert to kcal/mol using the molar mass.

I have an older CRC handbook, from the 80s (I don't remember the edition), I'm not doing 'groundbreaking research' so it is not necessary to know the
values for every single new compound that comes onto the market, so an older (and much cheaper) version is fine for me.
