Erratum.
In the abstract and in the text (line 35 in the middle column of page 185) of the report "Electrical resistivity and stoichiometry of K(chi)C(60) films" by G. P. Kochanski et al. (10 Jan., p. 184), the minimum resistivity was given incorrectly as 2.2 microohm-cm. The correct value is 2.2 milliohm-cm.
