The references here include useful reference data for some of the alkali atoms, including physical parameters and optical parameters for the D spectral lines, which are useful in atom cooling and trapping experiments. Also included are discussions of hyperfine structure and resonance fluorescence. All the data are presented with a self-consistent set of definitions to make them easy to use.
Please note that while I take care to ensure that the values in these references are as accurate as possible based on the available published data, these references should not be viewed as critical reviews, but rather as a compilation of recent, useful data.
Michael Gehm has put together similar data for Lithium 6 (fixed link, thanks to Ji Liu).
Tobias Tiecke has put together similar data for Potassium.
