Radical sharing: embracing the ideas that we are cultural stewards of the materials in our archives and libraries, and that our main role is to share that material with all who are interested. We are not in the business of gatekeeping. We are in the business of radical sharing. I am not calling on people to violate copyright, but I do think we need to push the envelope of risk in our organizations. Often, archivists and librarians could make a lot more of our material available online than we do, but because of the conservative risk profiles of our institutions, we often do not. I am calling for us to always think about reuse when we put material online: How might what we put up be reused by others?
