The strain on scientific publishing

TL;DR

The paper analyzes the increasing workload and publication volume in scientific publishing, revealing disproportionate growth, publisher strategies that accelerate this trend, and potential impacts on research quality and sustainability.

Contribution

It introduces five data-driven metrics to quantify publishing strain and highlights how publisher strategies and impact factor inflation contribute to this issue.

Findings

Publication volume has grown ~47% from 2016 to 2022.

Special issues reduce turnaround times, boosting article numbers.

Impact factors have inflated alongside publication growth.

Abstract

Scientists are increasingly overwhelmed by the volume of articles being published. Total articles indexed in Scopus and Web of Science have grown exponentially in recent years; in 2022 the article total was approximately ~47% higher than in 2016, which has outpaced the limited growth - if any - in the number of practising scientists. Thus, publication workload per scientist (writing, reviewing, editing) has increased dramatically. We define this problem as the strain on scientific publishing. To analyse this strain, we present five data-driven metrics showing publisher growth, processing times, and citation behaviours. We draw these data from web scrapes, requests for data from publishers, and material that is freely available through publisher websites. Our findings are based on millions of papers produced by leading academic publishers. We find specific groups have disproportionately grown in their articles published per year, contributing to this strain. Some publishers enabled this growth by adopting a strategy of hosting special issues, which publish articles with reduced turnaround times. Given pressures on researchers to publish or perish to be competitive for funding applications, this strain was likely amplified by these offers to publish more articles. We also observed widespread year-over-year inflation of journal impact factors coinciding with this strain, which risks confusing quality signals. Such exponential growth cannot be sustained. The metrics we define here should enable this evolving conversation to reach actionable solutions to address the strain on scientific publishing.
