Preservation Underground is the official blog of the Duke University Libraries Preservation & Conservation Departments. For readers in the libraries and archives world, the blog includes information about new job openings, internships, and conferences that may be of interest. The blog also highlights unique items in the libraries' collection. For instance, one recent blog post features a number of striking illustrations and graphics from the 1946 children's book Egg to Chick. Another recent blog post displays a Civil War era hat that was, unconventionally, uncovered in a manuscript box. Visitors may browse previous blog posts by category, including exhibits, quick pics, and technology.
