Wheaton Archives & Special Collections holds a wide variety of rare book collections, including more than 200 editions of John Bunyan’s Pilgrim’s Progress, many early texts by and about influential theologians and ministers like John Wesley and Jonathan Edwards, and hundreds of other manuscripts on Christian life, missions, art, and history. A few of these books also include inscriptions and marginalia – the scribbles, notes, and other markings made on the cover pages or in the margins of texts. These extra-textual materials often provide unique insights into the history of a book, as well as its impact.
