What is the journal impact factor?

The journal impact factor is based on the number of times that articles in a journal are cited in the two years following the year of publication. The impact factor of a journal is calculated by dividing the number of current year citations to the source items published in that journal during the previous two years.

Journal Citation Reports

Journal Citation Reports are part of the Web of Knowledge universe. They provide impact factors and times cited for journals for more than 10,000 of the world's most highly cited, peer reviewed journals in approximately 200 disciplines. High impact factor or highly cited journals are considered more prestigious and important.
