All About Mary is a digital encyclopedia that includes a wealth of information relating to the study of Mary and Catholicism. The introduction to the site reads: "Designed for everyone from expert theologians to those simply exploring, this tool, created and maintained by the International Marian Research Institute in partnership with the Marian Library at the University of Dayton, is the online destination for resources on the subject of the Blessed Virgin Mary and related topics." The site is keyword searchable, which will render results from the University of Dayton website. The thesaurus on the left-hand side of the page includes sections dedicated to film, literature, Marian symbols, theater, and much more. Those interested in the Marian Library should visit the link on the homepage. The library (also located at the University of Dayton) maintains an extensive digital collection of "digitized archival photographs, holy cards, stamps, ephemera, and other unique Marian materials," in addition to a collection of Marian art and a creche collection.
