Overlay journals: a study of the current landscape
Antti Mikael Rousi, Mikael Laakso

TL;DR
Overlay journals publish open access articles on repositories before peer review, with recent growth but still a small presence, mainly in sciences, often without author fees, potentially impacting scholarly publishing.
Contribution
This study provides a comprehensive overview of active overlay journals, their characteristics, and their current role in open access scholarly publishing.
Findings
34 overlay journals identified and analyzed.
Most are in natural sciences, mathematics, or computer sciences.
Overlay journals often do not charge author fees.
Abstract
Overlay journals are characterised by their articles being published on open access repositories, often already starting in their initial preprint form as a prerequisite for submission to the journal prior to initiating the peer-review process. In this study we aimed to identify currently active overlay journals and examine their characteristics. We utilised an explorative web search and contacted key service providers for additional information. The final sample consisted of 34 overlay journals. While the results show that new overlay journals have been actively established within recent years, the current presence of overlay journals remains diminutive compared to the overall number of open access journals. Most overlay journals publish articles in natural sciences, mathematics or computer sciences, and are commonly published by groups of academics rather than formal organisations.…
