The Marian Library/International Marian Research Institute
The Marian Library and International Marian Research Institute are two Catholic institutions of higher learning at the University of Dayton. They were previously one entity, but in 2017 returned to being administered independently. History. The Marian Library was founded in 1943, and is home to an extensive collection of books, periodicals, artwork, manuscripts, films, and ephemera related to the Blessed Virgin Mary. The Marian Library is located within Roesch Library at the University of Dayton, and is home to the International Marian Research Institute (IMRI), an institute dedicated to Mariology, or the study  of Mary. The International Marian Research Institute was founded in 1975 in affiliation with the Marianum, a Pontifical Institute in Rome, allowing students to study in America, instead of having to travel to Rome to complete their studies. IMRI's programs included a doctorate in sacred theology (S.T.D.) and licentiate in sacred theology (S.T.L.). IMRI stopped admitting new students to this program in 2016 and has closed the pontifical degree programs with the final commencement in August of 2021. Students, however, can continue to earn credits towards a master's degree through the Department of Religious Studies of the University  of Dayton. IMRI is also continuing to produce its Marian Forums, publishing the scholarly journal "Marian Library Studies." In 2021, IMRI ceased hosting Marian Studies and Spirituality, a weekly radio program on Radio Maria.<ref>Marian Studies and Spirituality on Radio Maria.
