Legal scholars and students can happily avoid expensive textbook costs with H20 Open Casebooks. Designed by Harvard Law School's Library Innovation Lab, H20 Open Casebooks enables law professors to create and share textbooks via a Creative Commons license. Professors have access to all of the case law cataloged by Harvard's CaseLaw Access Project (readers may remember this project from the 04-19-2019 Scout Report). This provides plenty of content to create casebooks on standard and niche areas of the law, without burdensome costs. Instructors new to the site may want to explore the Help Guide (linked on the home page), which offers written and video instructions. While a free account (and an academic institution email address) are required to create a textbook, anyone can access the existing casebooks. The "Search" button at the top of the home page invites users to browse the more than 250 casebooks available as of this write-up, which cover everything from "Advanced Intellectual Property/Cyberlaw" to "Animals and the Law in Canada."
