A popular chemical database distributed in printed form for 65 years by the National Institute of Standards and Technology (NIST) is now available online.

The NIST/TRC Thermodynamic Tables, distributed on a subscription basis through the NIST Standard Reference Data E-Commerce System, are available in two Web-based editions: professional and “lite.” The tables are reliable sources of critically evaluated thermophysical and thermochemical property data for pure, primarily organic, compounds. Researchers in government, academia, and industry can use the professional edition to find critically evaluated information about more than 50 thermophysical and thermochemical properties of 7,765 compounds. Annual license fees range from $1,200 to $2,500. The lite edition covers 150 commonly used compounds and annual license fees range from $200 to $1,500.
