Measurements of the total cross section of e+e- -> hadrons are presented in two different ranges of centre-of-mass energy. The measurements are made using the CLEO III and CLEO-c detectors at the Cornell Electron Storage Ring. The absolute cross sections and the values of R, the ratio of hadronic to muon pair production cross sections, are determined at seven centre-of-mass energies between 6.964 and 10.538 GeV. The total cross sections and values of R are also determined at thirteen centre-of-mass energies between 3.97 and 4.26 GeV; in addition, the inclusive and exclusive cross sections for D+, D0 and Ds+ production are presented. Furthermore, for the lower centre-of-mass energy range, exclusive cross-sections are presented for final states consisting of two charm mesons: DDbar, D*Dbar, DDbar*, D*Dbar*, Ds+Ds-, Ds*+Ds-, Ds+Ds*-, DDbar*pi and D*Dbar*pi.
