PLOS Biology at 20: Reflecting on the road we've traveled.

Why was PLOS Biology launched and how has it changed over the past 20 years? Three editors who have been at the helm of the journal reflect on its beginnings and evolution.

Systemic problems require systemic solutions: the need for coordination and cooperation to improve research quality.

Various factors contribute to low reproducibility and replicability of scientific findings. Whilst not all of these are necessarily problematic, there is growing acceptance that there is room for improvement. Many sectoral organisations have a role to play in this, by refining incentives and rewards, promoting specific behaviours such as open research practices, and exploring innovations in grant funding and scientific publishing. However, given the systems nature of the challenge, real change will require the coordination of these efforts, and partnerships that ensure alignment of activity and interoperability of training. Efforts to improve research quality will require investment, in infrastructure, training, and research on research to ensure that innovative solutions are evidence-based, and potential unintended consequences are explored (and avoided). National structures (e.g., the planned UK Committee on Research Integrity) should focus on understanding the research system, identifying areas for improvement, and promoting research to understand the impact of novel approaches and innovations, in order to advise on how to maximise benefit and avoid harm.

A data citation roadmap for scientific publishers.

This article presents a practical roadmap for scholarly publishers to implement data citation in accordance with the Joint Declaration of Data Citation Principles (JDDCP), a synopsis and harmonization of the recommendations of major science policy bodies. It was developed by the Publishers Early Adopters Expert Group as part of the Data Citation Implementation Pilot (DCIP) project, an initiative of FORCE11.org and the NIH BioCADDIE program. The structure of the roadmap presented here follows the "life of a paper" workflow and includes the categories Pre-submission, Submission, Production, and Publication. The roadmap is intended to be publisher-agnostic so that all publishers can use this as a starting point when implementing JDDCP-compliant data citation. Authors reading this roadmap will also better know what to expect from publishers and how to enable their own data citations to gain maximum impact, as well as complying with what will become increasingly common funder mandates on data transparency.

Meta-Research: Broadening the Scope of PLOS Biology.

In growing recognition of the importance of how scientific research is designed, performed, communicated, and evaluated, PLOS Biology announces a broadening of its scope to cover meta-research articles.
