[Factors of evaluation and interaction of scientific journals--impact factor and interjournal impact factor]. / Wskazniki oceny i wzajemnego oddzialywania czasopism naukowych - impact factor oraz interjournal impact factor.

The aim of the study was to analyse the extent of influence ofjournals with high Impact Factor (IF) into the world's science development. The survey was performed using Journal Citation Reports/Science Edition 1998-2001 database. One hundred journals with the highest IF were extracted and Interjournal Impact Factor (IIF) was made for each of them. It was proved that--regardless of the field the journals belong to--their influence into the filed and other periodicals should not be evaluated according to their IF value. It has been established to evaluate the journals, not particular articles. That's why we should not change its application and use it to express an opinion on the publications and scientific workers.
