These are broad categories of material and encompass a large percentage of special collections, including manuscripts, bound material, a variety of flat artwork and photographs. Paper based items should be photographed or scanned to 7200 pixels on the long axis, 300 500 PPI, minimum, generally not to exceed 9600 pixels long. This allows for predicting long-term storage needs based on the number of items in a collection or project. There are exceptions to this, such as scrolls, where 7200-9600 is appropriate for the short axis.
