You can export reference metadata and PDFs, but this won't include the notes you've made, these only exist in the cloud when using Lean Library Workspace.
To export your references:
- Select the references you want to export (use the checkboxes, or the master checkbox to select all references in a project or your entire account)
- and then click the copy/move/export button:
- And then select Export As... and choose the output format (RIS, BibTeX or CSV).
To download PDFs:
- Use the master checkbox (1) to select all references (if you're in the All references section you can select everything in your library, or you can export per project.
- Then simply click the copy/move/export button (2) and select Download PDFs:
This will download a .zip file containing all of the selected PDF files. Please note that PDFs are limited to 100 files/100MB per download, so you may need to export in batches.
