In an update to our previous post about SCImago journal rankings, we have news of updated rankings for some of our journals. Highlights of these include high rankings for the following BMC-series journals:

• BMC Bioinformatics with a SCImago Journal Rank (SJR) of 0.75 is placed 2nd of 150 journals in the Computer Science Applications category.
• BMC Medical Education (SJR 0.13) is 2nd of 397 journals in the Education category.
• BMC Medical Ethics (SJR
  of 0.11) is 1st of 9 journals in the Issues, Ethics and Legal Aspects
  category. Philosophy, Ethics and Humanities in Medicine, which is also
  published by BioMed Central, occupies the 2nd place in this category.
• BMC Plant Biology (SJR 0.67) is 8th of 291 journals in the Plant Science category.

These updates to the 2008 SCImago journal rankings have been released as these journals were previously listed in categories that were not as relevant to their scope.

The SCImago Journal Rank (SJR) is a measure of a journals’ citation impact and is calculated in a similar manner to Google’s Page Rank. This approach calculates a journal rank by weighting citations from journals according to how highly cited the journal is itself. Further details of SJRs for BioMed Central journals can be found on our website.
