Research protocols refer to a variety of procedure descriptions, including (but not limited to) guidelines, best practices, suggested workflows, safety precautions, animal handling, and any other method related to research and education.
Repository
Open Science Framework (OSF) : Open platform (from the Center for Open Science) that can be used for sharing protocols, but also papers, preprints, code, and data.
protocols.io : A for profit repository for publishing protocols. There is a free academic plan for public sharing (private and secure workspaces have a fee).
Protocol Exchange : Open repository (from Nature Portfolio) for sharing scientific research protocols from any branch of the natural sciences. All uploaded protocols are made freely available to the scientific community for use and comment and are assigned a DOI for citation purposes.
Scientific Protocols : Open repository (part of the Reproducibility Initiative) built on the GitHub API. This allows researchers to leverage the full power of GitHub to monitor changes to a protocol over time, fork a protocol to create a new one based on an original, and save your favorite protocols for easy retrieval.
Peer reviewed journals
bio-protocol : Publishes step-by-step protocols in any area of life sciences. One criteria for publication is whether the protocol has been validated by its use in a published research article (strategic partner with Science/AAAS).
Current Protocols : Covers the range of life sciences protocols needed for interdisciplinary research. Current Protocols encourages researchers who have developed robust protocols to submit a proposal or pre-submission inquiry to ascertain the suitability of the method for inclusion.
JoVE : Articles are video based but also include a detailed text protocol and representative results. There is a publication fee for all articles.
Nature Methods : Peer-reviewed journal that publishes novel methods and significant improvements to basic life sciences research techniques.
Nature Protocols : Publishes detailed step-by-step protocols that have been proven to work already.
Nature Reviews Methods Primers : Primers are introductory overviews of methods and techniques that include best practices for experimentation, analysis, and applications. Each Primer is accompanied by a PrimeView, an illustrated summary of the article with original artwork produced by the editorial team.
