ASM Journals and The Journal Impact Factor (JIF)

The mission of the ASM Journals program is to advance the microbiological sciences through the pursuit of scientific knowledge and dissemination of the results of fundamental and applied research. ASM journals publish high-quality research that has been rigorously peer reviewed by experts and evaluated by academic editors who are working scientists drawn from eminent institutions around the world.  Known for their quality, rigor, and fairness, ASM Journals continue to provide current, influential coverage of basic and clinical microbial research.

Articles published in the ASM journals receive international media attention and have been featured in the New York Times, Science Magazine, Los Angeles Times, CNN, National Public Radio (NPR), CNBC, and dozens of other media outlets.

As announced in a shared editorial published in 2016 (below), the ASM Journals Editors in Chief and Society leadership have decided that Journal Impact Factors (JIFs) will no longer be posted to the journal websites or used in advertising. Our goal is to stop contributing further to the misuse of JIF as a proxy for evaluating the quality of an individual's scientific research.  However, JIFs for ASM Journals continued to be assigned and published every June by Clarivate Analytics' Journal Citation Reports (JCR).   ASM Journals staff also can provide JIFs upon request.

Clarivate Analytics reports the following data on ASM’s journals in the most recent Journal Citation Reports®(JCR):

  • ASM journals publish over 15% of all articles in Microbiology, while accounting for 31% of all Microbiology citations
  • ASM publishes the 4 most highly cited journals in Microbiology: AAC, AEM, JB, and JCM.  
  • ASM publishes the top-cited journal in Biotechnology & Applied Microbiology [AEM], Pharmacology & Pharmacy [AAC] and Virology [JVI])
  • ASM publishes the #1 journal ranked by Eigenfactor® in Pharmacology & Pharmacy [AAC] andVirology [JVI]
