Publishing Metrics Update 2023
10 July 2023
We are pleased to share the latest metrics updates for Microbiology Society publications following another year of fantastic content across the portfolio.
As a signatory to the San Francisco Declaration on Research Assessment (DORA), we suggest that no metric should be used in isolation to assess the value and impact of research. As each metric reflects a different aspect of the titles in our portfolio, we present these together to provide fuller context and a richer view of their performance.
We thank all of our authors, Editors and Reviewers, as well as the staff and members of the Microbiology Society, for supporting and advocating for society publishing. Every paper we publish not only reflects the commitment and expertise of our community to provide quality research, but also helps us to raise funds to support microbiologists at all career stages with grants, events and professional development.
We are a not-for-profit: publish with the Microbiology Society to make a difference to your community.

Definitions
- 2-year Journal Impact Factor: The Journal Impact Factor is defined as all citations to the journal in the current JCR year to items published in the previous two years, divided by the total number of scholarly items (these comprise articles, reviews, and proceedings papers) published in the journal in the previous two years.
- 5-year Impact Factor: The 5-year journal Impact Factor is the average number of times articles from the journal published in the past five years have been cited in the JCR year. It is calculated by dividing the number of citations in the JCR year by the total number of articles published in the five previous years.
- Immediacy Index: The Immediacy Index is the average number of times an article is cited in the year it is published.
- Cited half-life: The median age of the articles that were cited in the JCR year. Half of a journal's cited articles were published more recently than the cited half-life.
- CiteScore: CiteScore measures average citations received per document published in the serial.
- SNIP (Source Normalized Impact per Paper): The SNIP measures actual citations received relative to citations expected for the serial’s subject field.
- Full-text downloads: How many times articles in that journal were accessed in 2021.
- Altmetrics: Altmetrics are non-traditional metrics proposed as an alternative to citation impact metrics. A paper’s Altmetric score is a weighted measure of its mentions in the press and on social media, among others, and is displayed on each article page. We specifically calculated the scores based on publication dates in 2021, and took the current Altmetric scores as at 12 July 2022. We urge people to evaluate each article individually for its reach in social media and news sites by using the Altmetrics widget on each article page.
