The correspondence is almost exclusively between Ware and William E. Connelley. They discuss their various research and publications, personal and business matters, and on Kansas and national politics.

Sara Robinson's letters to Phebe Stone, her sister-in-law, were written while her husband Charles Robinson was in California. Her letters to Frank Blackmar mention a history written about the University of Kansas, events at the University, books about Kansas, property holdings and taxes, and farm management and expenses.

Correspondence, research notes, interviews, manuscript drafts, and photographs, covering the years 1883-1914, from an early Kansas historian.
