Primarily a collection of correspondence, business papers, diaries, journals, essays, etc., of Horatio Gates Warner (1801-1876) and his immediate family.

Finks' papers collected in Rare Books/Special Collections begin with writings by David Finks and then move to documentation of Finks' life and work, including material and some correspondence relating to Catholic Council of Urban Ministries, Campaign for Human Development, and the Downtown (Rochester) Community Forum. Next are Finks' personal records which are combined elements of both a journal and a scrapbook. Contained in binders, they are a combination of journal entries, articles, letters, cards, flyers, programs, and anything else that was meaningful to him. There are a few gaps, but the journals cover from 1985-2007. Finally, the last few boxes are articles and letters regarding people and issues, largely religious, of interest to Finks as well as personal correspondence and photographs.
