Alert COVID-19 Update

Harvard University and Harvard Law School will shift to remote teaching and learning beginning Monday, March 23. For more information and the latest updates, please visit the HLS coronavirus information page.


H2O allows users – faculty or students – to develop, remix, and share online textbooks and casebooks under a Creative Commons license.

Any content, or sequenced content (known in H2O as a playlist), can be accessed and built upon by other users. H2O has a range of tools that allow you to edit, highlight, annotate and organize a range of content types, including links, PDFs and cases. This platform, developed by the Berkman Center and the Harvard Law School Library, frees the instructors from needing outside supplemental materials, and they can skip huge swaths of casebooks, since the content can be tailored to fit a class’ specific needs. Currently, H2O is geared primarily toward law professors, though the platform can be used across intellectual domains. Contact Brett Johnson at or visit the H2O website to get started.
