Another reason why libraries have not done more in #p2p may be: they don't provide their own content so they cannot freely share it without restrictions. This could change with #opendata such as research data. One of the rare recent publication I could find is https://doi.org/10.5281/zenodo.7646355 (application of #IPFS for research data in @nfdi4earth #nfdi) - see https://www.dkrz.de/de/kommunikation/aktuelles/ipfs-pinning
