In 1992-2000, data on e+e-annihilation into hadrons were collected in the energy range 0.36 < sqrt(s) < 1.4 GeV with the CMD-2 and SND detectors at the VEPP-2M collider in Novosibirsk. The results of the R (s) measurements in these experiments are presented. © 2008 Elsevier B.V. All rights reserved.
