Data Archiving & Self-Archiving Permissions

Maximize your nutrition research impact through open data sharing and self-archiving

Authors of nutrition research published in IJN have unlimited self-archiving rights:

IJN strongly encourages authors to make underlying nutrition research data publicly available to:

• Enable independent verification and replication of findings
• Facilitate meta-analyses and systematic reviews
• Maximize research impact and citations
• Comply with funder open data mandates
• Advance nutrition science through data reuse

• Zenodo (zenodo.org) - General-purpose, DOI-minting repository
• Figshare (figshare.com) - Datasets, figures, tables, code
• Dryad (datadryad.org) - Curated data repository with DOIs
• Open Science Framework (OSF) (osf.io) - Complete project archiving
• GitHub (github.com) - Code, analysis scripts, computational methods
• USDA FoodData Central - Nutrition composition databases
• NIH Data Sharing Repositories - For NIH-funded research

Data availability statements: Include a data availability statement in your manuscript describing where readers can access underlying data.

Which versions can you archive?

• Preprint/Submitted Version: ✓ Anytime, anywhere
• Accepted Manuscript (post-peer review): ✓ Immediately upon acceptance
• Published Version of Record (final PDF): ✓ Immediately upon publication
