Adding new cases

H2O has nearly 4,000 cases — with more added every week — that users can edit by making a collage of the case and then applying their own layers, annotations, and highlights. The H2O team adds all cases into the platform. If H2O doesn’t have a case that you’d like to use, there are two ways that it can be added.

1. The preferred route is to send an e-mail to with a list of cases that you want to be added to H2O (please include, if possible, the short name and citation of each case).

2. The other option is to request a case via H2O itself. Login to your user account, then navigate to the cases section (by clicking the cases icon at the top of the window). Once you’re in the cases section, there should be a “Request case” button next to the search field. Click the “Request case” button, provide the relevant information for the case, and hit submit.

Requesting cases

Every week, we add to the H2O database of cases. If a case that you want to collage and add to a playlist isn’t available in H2O yet, you can request it by filling out and submitting a short form here. (Note: you will need to be logged in as a user to request cases.) Once you request a case, you should receive an e-mail notifying you that the case request has been submitted (if you don’t, please let us know!). We will try to locate and ingest the case into our database as soon as possible.

If you need a specific case really quickly, in addition to submitting the request via the form above, please also send us an e-mail to h2o [at] cyber [dot] law [dot] harvard [dot] edu, and we’ll try to get it as a priority item.

By the way, if you see that a case has a typographical error, please let us know by clicking on the “Report Error” button at the side of the window. We are implementing a system so that we can emend those errors. It’s a little tricky to do technically, especially once a case has been collaged, but our crackerjack developers have created a way to do so by versioning cases.
