Review of Atomic Weights and Historical Tables

On an element by element basis, CIAAW performs an extensive review of the atomic weights.  Because of the magnitude of this endeavor, this task is performed at approximately 20-years intervals.  The last review was performed in 2000 and published in 2003.

The penultimate review was published in 1984.

Since 1882, atomic-weight values have improved.  A discussion of their improvements is presented in:
