- Abstract
- Introduces the standard impact factor for particular fields of science (Ig) and the relative impact factor K for scientific journals. The technique for the calculation of the standard impact factor for a field is an inherent part of a methods which allows a cross field evaluation of scientific journals. This method for evaluating scientific journals elaborated in 1988 was aimed at the analysis of Russian journals covered by the SCI database; it was also used for chemical journals and for journals in the life sciences
