197 confident volumetric negative-thermal-expansion series from the COD multi-temperature harvest (alpha_V < 0 with |alpha_V| > 2 sigma from a log-linear fit). Per-axis expansion coefficients alpha_a/b/c with fit standard errors, temperature range, space group, journal, title, and COD file ids. Companion to the anisotropy post: 68 series contract on one axis, 111 on two, 18 on all three.
