If you’re looking to buy or borrow a DVD copy of either “How to Die in Oregon” or “Hot Coffee, the Movie,” please check the documentary’s website for ordering and availability information.
In the fullness of time, public libraries will have these DVDs in their collections, but documentary and independent film distribution business models are different from mainstream movie rollouts.
You can also check your own library’s catalog or use Worldcat dot org for a wider, though imperfect, library catalog check.
Research note: You can research the Oregon Death with Dignity Act online. The state’s webpage URLs change occasionally so I recommend you use a search engine, e.g. Google, to search “oregon death with dignity” act or law
