No secrets? No problem. The Cornerstone is our all-access guide to everything Delta Upsilon.
Since 1916, Delta Upsilon members have enjoyed the benefit of a standard manual published by the Fraternity to assist members and associate members in their college experience, and to learn about the Principles, history and values of Delta Upsilon.
In 1987, after many years of revisions, a committee was formed to pursue further development of a member manual that would more carefully consider the growing needs of young men entering pledgeship and membership in Delta Upsilon—not only their needs to learn about and understand their new Fraternity, but also to feel confident in their abilities to successfully complete their undergraduate studies.
The final result was a new name and a new identity to the Fraternity's member manual. The 24th edition of the manual was rebranded as The Cornerstone.
Since that time, The Cornerstone has been updated numerous times, the latest in summer 2023. This version includes the Fraternity's enhanced educational programs portfolio, updated awards program and the Men of Merit initiative.
