Designed as part of the Yale Divinity Digital Image and Text Library, the AdHoc Image and Text Database is a web-searchable database that contains electronic images and texts related to the history of Christianity. Visitors may begin looking for relevant materials by a keyword search, or decide to peruse a list of categories for browsing. The categories available include listings organized by geographical area, historical area, object type, or topic. These four divisions include topics such as Religious Doctrines and Practices, Missions and World Christianity and People. Some of the materials here are restricted to the Yale community solely, but many of the images (and a few of the texts) are available for the general public. Quite a number of the visual materials here are quite fascinating, such as a 1879 map of Calcutta that shows the location of churches, schools, and government offices and another map that shows the location of Protestant mission stations in China.
