Many forms of hand-written and printed documents are represented in this series, and include indentures, agreements, articles of association and agreement, deeds, receipts, sketches, official reports of corporations, announcements (as by railroad and telegraph companies), petitions, stock transfers, notice of legal proceedings, blueprints, small broadsides, hand-drawn maps, legislative bill announcements, lithographic drawings, drafts of speeches, hand-written copies of outgoing letters assembled for legal purposes, and many other kinds of material. Most of these pertain to Cornell's involvement with the telegraphic industry and the founding of the University; others concern New York State legislation and Cornell family matters.
