Henry Dickinson's Book contains undated essays and poetry composed by Henry Dickinson, as well as a register of boys and girls who attended the Westtown ("Weston") School in West Chester, Pennsylvania, between 1799 and 1805.
The first section (21 pages), entitled "Henry Dickinson's Piece Book," contains essays, epigrams, and poetic excerpts, often dealing with religious topics. One essay, entitled "Carianers," examines the native people of the Ava Kingdom, in what is now Myanmar (Burma).
The remainder of the book, beginning from the opposite cover, is labeled "Henry Dickinson's Book" and consists of ledgers of female and male students admitted to the Westtown School between 1799 and 1805. This register is divided by gender, and covers approximately 500 female students (31 pages) and 430 male students (23 pages). Each name is accompanied by the individual's student number, age, parents' names, and place of residence. Henry Dickinson is listed as number 329 in the list of male students. Most of the students came from the area around Philadelphia, and several came from Wilmington, Delaware. Near the end, both ledgers have several skipped or incomplete entries.
