The O’Meara Mathematics Library served as a departmental branch library from 1952 until 2020, with most of the collection directed toward supporting faculty and graduate student research. It also housed the [Morse collection](https://curate.nd.edu/show/9593tt47f1c). In June 2020, the branch library in Hayes-Healey Hall closed, and the collections and services were relocated to the Hesburgh Library.
