October 11, 2019 - JCR Data Update

2018 Data Update

After JCR data were published in June 2019, we were able to obtain materials whose absence had prevented journals from receiving a Journal Impact Factor, as well as to correct metrics for a small number of journals.  The 2018 JCR data (2019 release) are now complete and all updates have been fully incorporated into the product.

During production for the 2018 data reload we found a small number of expected updates were not successfully implemented in time to be reflected in the citation counts for J PEDIAT INF DIS SOC.  The following metrics are official data, and include all citations associated with those updates.

J PEDIAT INF DIS SOC

  • Total citations:                971 
  • Journal Impact Factor:    2.443
