An interactive map of the 1M most-assigned books in college syllabi

The citation graph of the ~1M most-assigned books and articles (node2vec -> UMAP).

An interactive map of the 1M most-assigned books in college syllabi launched on February 14, 2021 with 21 votes, #1,150 of 3,133 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 5 years on.

In plain words

An interactive map visualization showing the one million books most frequently assigned across college syllabi. The tool helps students, educators, and researchers explore which texts appear most often in academic coursework and discover connections between different fields of study. Users can search, filter, and navigate the collection to understand reading patterns across higher education.

    Hey HN! I love finding new books to read on here. I wanted to gather the most mentioned books and recreate the serendipity of physical browsing. I scraped 20k comments from HN threads related to reading, extracted the references and opinions using GPT-4o mini, and visualised their embeddings as a map. - OpenAI's embeddings were processed using UMAP and HDBSCAN. A direct 2D projection from the text embeddings didn't yield visually interesting results. Instead, HDBSCAN is first applied on a high-dimensional projection. Those clusters tend to correspond to different genres. The genre…

    When I read papers, I have to jump between multiple tabs to find the dataset, code, videos, peer reviews, and so on. I tried to fix this with this project. It started as a project just for papers on arXiv, but after its initial success on Twitter (got like 1.9k views: the most I have gotten for a post), I have now expanded it to include other openly available papers from PubMed Central, bioRxiv, medRxiv, and eLife. These papers have been linked with their genes, proteins, diseases, drugs, clinical trials, 3D protein structures, code, and cited and similar papers. This project now has four…
