The Index of Christian Art database presently contains over 20,000 work of art records which are accompanied by over sixty thousand images in color and black and white. Many of these images have never before been digitized and are published here for the first time. The Index records works of art produced without geographical limitations from early apostolic times up to A.D. 1400 (extended in the case of the Morgan and Princeton Library projects to include this manuscript holdings up to the end of the sixteenth century). There is a particular emphasis and focus on art of the western world. Seventeen different media are represented in the archive, and these include manuscripts, metalwork, sculpture, painting, glass, and so forth. Access to the database is possible on a predetermined number of levels from Browse to Simple Find to Advanced Find Level catering to the inexperienced to the expert user. The database is periodically updated as works of art are catalogued.

There are approximately 60,000 images in the collection.
