To find resources on mariology in the catalog, select the "Subject" search on the Advanced Search page. Some of the terms you would use include "Mary," "Mother of God," "Marian," and "Mariology."
Depending on your topic, you can narrow down your searching even further by adding subdivisions. You could also change the results by the format of the book, adding terms like "Encyclopedias," "Handbooks, manuals, etc.," and "Dictionaries" to the end, bringing back just those types of items.
Broadening your search could be beneficial as well, including topics like "rosary," "blessed virgin," "saints," and "religious shrines."

BT595-680- Mary, Mother of Jesus Christ. Mariology
BT650-660- Miracles. Apparitions. Shrines, sanctuaries, images, processions, etc.
