The Derso and Kelen Collection consists of correspondence, writings, published material, and over 900 cartoons and caricatures in varying media ranging from pencil sketches and ink drawings to richly-hued watercolors and limited edition lithographic portfolios created by the Hungarian caricaturists and political satirists Alois Derso and Emery Kelen.

The collection contains manuscripts related to four generations of the Blanco White family, spanning two centuries: including works, diaries, correspondence, documents, accounts and expense records, and printed material. Joseph Blanco White, the Spanish-English writer and religious figure, remains the focus of the collection; however, his brother Fernando, a politician and intellectual of 19th-century Seville, also accounts for a substantial part of the material. Of particular interest are autograph manuscripts of several of Joseph's literary efforts, as well as other genealogical material relating to the Blanco White family.

This collection consists of virtually all of the surviving records of Scribners (1846-1984), the New York City publisher, and reflect aspects of all of its publishing functions (soliciting and acquiring books, editing manuscripts, printing and manufacturing books, advertising and publicizing publications) and business concerns (book and magazine publisher, retail bookstore, subscription books department, educational books department, printing press and bindery, rare books department). Included are files of editorial correspondence with authors, manufacturing records about book production, advertising records, author contracts, a collection of dust jackets, book catalogs, ledgers, and photographs. While there are gaps in most of the series or record groups, there are records representative of all of the firm's former permutations: Baker & Scribner, Charles Scribner & Co., Scribner, Armstrong & Co., Scribner, Armstrong & Welford, Scribner & Co., Charles Scribner's Sons. The bulk of the material (1880s-1970s), however, dates from the period when the publisher bore its most familiar name, "Charles Scribner's Sons." There is also material related to early publishers' organizations and international copyright.
