Digital libraries at research universities make use of a wide range of unique tools to enable the sharing of eclectic sets of texts, images, audio, video, and other digital objects. Presenting these assorted local treasures to the world can be a challenge, since text is often siloed with text, images with images, and so on, such that per type, there may be separate user experiences in a variety of unique discovery interfaces. One common tool that has been developed in recent years to
