2019 Data Update

After JCR data were published in June 2020, 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 2019 JCR data (2020 release) are now complete and all updates have been fully incorporated into the product.
