"It's our contribution to the ongoing effort to rescue, preserve and make open endangered government materials at risk of disappearing…Our focus will be on policy and technical reports, papers, documents, blogposts, videos, and podcasts but we're open to suggestions for other content types - except for datasets. There are a number of excellent ongoing efforts to rescue data so there's no need for us to replicate them…Our goal is to make these materials easy to find and permanently available…We’re calling on librarians and researchers to help identify endangered materials from government agencies and suggest at-risk websites and repositories. We're also inviting those who have been working closely with agencies to send us copies of previously open materials they may have on their hard drives and laptops."
