Volume III/15 deals with data on the transport phenomena in metals, filling a long-felt need for both experimentalists and theoreticians. The first two subvolumes, III/15a and III/15b, contain information on the electrical conductivity of metals and related subjects. The present subvolume III/15c covers the thermal conductivity, its electronic part as well as the lattice contribution. It updates and complements the corresponding chapter in volume II/5b of Landolt-Börnstein, 6th Edition, published in 1968.
