The primary objectives of the Prange Collection are to preserve and provide access to the materials. After the materials are reformatted for preservation purposes (on microfilm or digital images), the original materials are kept for their shelf-life. In the majority of cases, the materials are not conserved. In order to reshelve the books after scanning, many need to be put in an enclosure. Originally, the books were rehoused in pre-made tux boxes made of card stock. That made it difficult to browse the shelves. Now, a Prange staff member custom-makes tux boxes out of Mylar, a polyester film. Creating the Mylar box is labor intensive. It can take 1.5 hours per box.
The slideshow shows the process of creating a Mylar tux box.
