Atla: Cooperative Digital Resources Initiative (CDRI)The Cooperative Digital Resources Initiative of the American Theological Library Association and Association of Theological Schools is a collection of digital resources contributed by member libraries. The creation of CDRI was made possible by a generous grant from the Henry Luce Foundation. The CDRI collections provide access to digital images of woodcuts, photographs, slides, papyri, coins, maps, postcards, manuscripts, lithographs, sermons, shape-note tune books, and various forms of Christian art, architecture, and iconography.
