The NIST-JANAF Thermochemical Tables website is on an online resource that contains the contents of the NIST-JANAF Thermochemical Tables printed volumes. This website is a resource for sharing the data from the work that went into producing the volumes, not as a resource for the most up-to-date thermochemical data available. This is intended as a historic archive for an incredibly valuable resource that continues to have value today.
