CEON WoS Impact Factor: A new-old indicator for SCIndeks non-WoS-indexed journals

In the 2016 edition of the Journal Bibliometric Report (JBR), CEON/CEES has introduced, among other innovations, two new impact indicators: CEON WoS Impact Factor 2 and CEON WoS Impact Factor 5. The new indicators are calculated and displayed for all journals indexed in SCIndeks. For the journals indexed in the Web of Science (WoS), the values of these indicators are taken from the Journal Citation Reports (JCR). For the other journals, they are calculated based on citations found in the Web of Science and the number of papers published in SCIndeks journals over the past two/five years.
