Fifty years after its original German publication, Brill launched a free beta period for the Lexikon der christlichen Ikonographie online.
Included are links to other resources, like the Princeton Index of Medieval Art, that map the LCI lemmas to relevant entries in the IMA, and that are also indexed by ICONCLASS notation. The LCI is working on adding better quality images, all under Open Access on the homepage, for those works mentioned in the texts.
