JOURNAL CITATION REPORTS AND IMPACT FACTORS

IMPACT FACTORS

The Institute for Scientific Information (ISI) analyzes journal citation patterns to determine "Impact Factors" and "Half-Life" values for each journal. The impact factor is used to measure the importance of individual journals relative to other titles in their field. The annual Journal Citation Reports for Sciences and Social Sciences journals compile these data into ratings and ranked lists of journals.
