[2] By the late eighteenth century, all incoming freshmen became members either of Linonia or its rival society, Brothers in Unity, which was founded in 1768.

Linonia was reconstituted multiple times throughout the 20th century,[4][5] with its current form taking the shape of Yale's other undergraduate secret societies.

Unlike many secret societies whose focus is the members' biographies, Linonia meetings often involve debate on intellectual and political topics.

[citation needed] In 1871, Linonia and Brothers donated their literary collections to the university's new central library, then shut down.

Both societies had kept substantial collections of works not deemed suitable by the Yale faculty, which did not teach English literature until the late nineteenth century.
