Journal Metric Values

In this section you can find the entire collection of journals covered by Scopus (currently the largest database of academic literature with 21,900 journals from 5,000 publishers) along with their SNIP, IPP and SJR metrics going back to 1999.

Due to the fact that journal metrics are calculated from Scopus, the journal metric values cannot be fixed in time. Scopus is dynamic: it shows citations per document in real time and is continuously updating historical content, in addition to new content as it comes out. As a consequence, when the values are published, they will take all the historical updates into account as well. This means that with each data refresh, all values (current and previous years) are recalculated and refreshed. This is good if you want up-to-the-minute values, but can make it difficult to validate quoted values.

While we believe that reporting the current state of the database to be more transparent, we also realize that reports have been created based on previous metric sets. For this purpose historical datasets are maintained in this archive thus allowing for validation of past values.

Also, since 2012 SNIP and SJR values are being calculated using a modified algorithm. Read more on these changes on the about journal metrics pages
