The ATLA Religion Database (formerly ATLA Religion Index) indexes more than 600 of the leading journals in the field of religion and theology. The index also includes essays from multi-author works and book reviews. ATLAS (= ATLA Serials) has full-text content from approximately 190 journals. Most of these are full-text back to 1949 and indexed from 1908, although some do not include the most recent 1-5 years. (Updated semiannually)
