With the topic of religion magnificently on display in the Library's exhibition Three Faiths: Judaism, Christianity, Islam, the following images, selected from the Library's Photography Collection, take a look at those hard at work in the service of God.

The Photography Collection holds some 500,000 photographs spanning the medium's history and representing all major photographic processes from the daguerreotype to digital images. Currently on view at the Library is Recollection: Thirty Years of Photography at The New York Public Library.
