"Annotated catalog of hyperlinks for research in fields related to religion. This index is designed as a tool for students with little time. It analyzes & highlights important content of religion-related websites to speed research. Hyperlinks are provided not only to homepages but to major subsites, directories & documents within. Our purpose is not to circumvent tours of worthy sites, but to cut down the time spent on surfing, click-through, and sorting of gopher searches. "
