IMPORTANT: The ICSP and the Microbiology Society are pleased to announce that our appeal against Clarivate's decision to suppress the journal from the 2019 Journal Citation Reports has been successful. International Journal of Systematic and Evolutionary Microbiology will be reinstated in the 2019 Journal Citation Reports (JCR) – the journal's metrics can be found on our Article and journal metrics page.
