Spectacle is a slide show generator that allows a user to find images from Harvard collections and incorporate them into an online slideshow with links to library metadata and collection information. It can be used by anyone to gather together public-domain and Harvard-owned images, ranging from photographs to manuscript pages to ephemera. Benefits include providing an easy way to gather images and share them online, the ability to run collections of images on kiosks and idle workstations, support for assembly of online exhibits without technical staff, and easy creation of image collections for classroom instruction and supplemental course resources.
