The records of the Calliopean Society document its history through minutes of meetings, legal documents, catalogs of members, librarians' records, and financial records. In addition to meeting minutes, 1819-1853, the bound volumes also contain revised constitutions and histories of the Society. Minutes of the last several weeks were written on single sheets of paper and are filed in a separate folder. Additional copies of revised constitutions and bylaws are found in separately bound volumes.
Librarians' records, 1830-1851, consist of catalogs of books, reports on acquisitions of new books, and circulation records.
Financial records, 1819 to 1855, document purchases, membership fines, and summaries of income and expenses.
Correspondence, 1837-1852, by the officers documents relations between the Society and Yale.
Exhibition records, 1820-1835, detail the dramatic, poetic, and oratorical activities of the Society.
The addition consists of one oration from 1825.
