History & humanitiesfree + paid
The go-to index for philosophy literature, with category-based browsing. Many entries link open-access PDFs you can drop straight into a notebook.
Built and curated by philosophers, so its category tree reflects how the field divides itself rather than a generic subject taxonomy. That makes it the fastest way to assemble a reading list for a notebook on a specific philosophical question. Many entries are bibliography only, though, so check whether the linked PDF is really open before counting on it.
Import into Gemini Notebook

Archives return scans and item pages rather than clean text — look for a transcript, PDF, or article summary before importing the artifact page itself.
