The article discusses the significance of impact factor (IF) in judging the value of a scientific journal. IF is a product of the Institute of Scientific Information. To calculate the IF of a journal, the total number of citations in a particular year to the articles published in the preceding two years in the journal is divided by the total number of source item published in the preceding two years. One of the factors that may affect the calculation is the preference for English language.
