The worldwide data on electron-positron interactions at energies greater than 100 MeV are critically reviewed by an international author team. The data cover the period from 1970 to the middle of 1990. The authors concentrated on lepton and hadron data, because there is a lot of data concerning lepton and hadron channels in electron-positron annihilation. Furthermore, because data on lepton final states are very important for a comparison with the predictions from the Standard Model of elctroweak interactions. Careful corrections and error analysis, which have been applied for the final presentation of the data is explained in detail together with theoretical concepts.
