Catalogue of a Collection of Works on Ritualism and Doctrinal Theology, Presented by John Harvey Treat

This catalogue was published in 1904 as part of the Library of Harvard University's Bibliographical Contributions series. It documents a significant donation made by John Harvey Treat, a dedicated bibliophile and scholar of ecclesiastical history, to the Harvard College Library. The collection itself focused heavily on the theological debates and liturgical practices surrounding ritualism, a movement within the Anglican Church that sought to restore traditional, often Roman Catholic-influenced, ceremonial practices during the 19th century.

William Coolidge Lane, who served as the Librarian of Harvard College, curated and edited the volume. Lane was instrumental in professionalizing the library's cataloging systems during his tenure. He approached the bibliography as a scholarly resource intended to provide researchers with access to Treat's extensive and somewhat esoteric assembly of pamphlets, sermons, and doctrinal tracts. The work reflects the era's commitment to preserving specialized subject collections for future academic inquiry and remains a primary reference for understanding the scope of late 19th-century theological scholarship.
