This single notebook was for the most part written by William Woodhull (1741-1824), Class of 1764. The bulk of the book consists of recipes for medicinal prescriptions, catechisms, student orations and a poem. A good deal of the book appears to have been written during Woodhull's days at Princeton, but some of the recipes date to 1850, beyond Woodhull's death and so were entered by another unidentified individual.

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.
