Data & official recordsfree
Where researchers post preregistrations, preprints, and project files. Project pages often hold the materials and data a published paper leaves out.
OSF is where a lot of empirical researchers post the material a published paper doesn't include: preregistrations, raw data, analysis code, sometimes drafts that never got published. A notebook checking whether a study's results match what was originally planned benefits from pulling the preregistration alongside the paper. Not every project is public, and quality varies since anyone can host a project there, published or not.
Import into Gemini Notebook
- 1Copy the link above (or a specific page from the site).
- 2In your notebook, click Add source → Website.
- 3Paste the link and confirm — several links can be pasted at once, one per line.
Gemini Notebook is a reading tool, not a spreadsheet engine — feed it the written reports and summary pages, not raw CSVs, and ask about what the documents say.
