Katie Fortney has made "Towards an Open Source Legal Operating System" available on SSRN.
Here's the abstract:
An informed democratic society needs open access to the law, but states' attempts to protect copyright interests in their laws are a major roadblock. This article urges broader access, analyzes the implications and legal arguments for and against copyright in the law, and considers strategies for access advocacy.
