# Connected Papers as a Gemini Notebook source > Builds a visual graph of papers related to one you pick.

Good for finding what to read next — then add the actual PDFs or abstract pages to Gemini Notebook. Starting from one paper, it builds a visual graph of related work based on shared citations, which surfaces adjacent papers a keyword search would likely miss. That makes it a useful step before you decide which papers belong in a notebook, not a source in itself. The graph is built from citation overlap, so very recent papers that haven't accumulated citations yet tend to be underrepresented. ## Import into Gemini Notebook 1. Copy the link: https://www.connectedpapers.com 2. In your notebook, click Add source → Website. 3. Paste the link and confirm — several links can be pasted at once, one per line. **Tip:** Gemini Notebook reads the text of the page you give it. Paste pages that carry the full text (an arXiv abs page, a PubMed Central article) — a paywalled landing page imports as just an abstract. ## More academic papers sources - [Google Scholar](https://gemini-notebook-hub.online/sources/google-scholar.md) — The widest net for finding papers across every field; follow its links to a full-text version before importing. - [arXiv](https://gemini-notebook-hub.online/sources/arxiv.md) — Preprints for AI, CS, math and physics. Paste the abs page URL as a Website source — figures survive that route better than an uploaded PDF. - [Semantic Scholar](https://gemini-notebook-hub.online/sources/semantic-scholar.md) — AI-assisted paper discovery with citation graphs — good for building the reading list before you build the notebook. - [PubMed Central](https://gemini-notebook-hub.online/sources/pubmed-central.md) — Free full-text biomedical papers — unlike PubMed proper, articles here import complete, not as abstracts. - [SSRN](https://gemini-notebook-hub.online/sources/ssrn.md) — Working papers in economics, law, finance and the social sciences, most downloadable as full-text PDFs. - [Academia.edu](https://gemini-notebook-hub.online/sources/academia-edu.md) — Researcher-uploaded papers across every discipline.
