The catalogues, lists, and accession records series consists of bound volumes and other materials which document the growth and classification of the University Library's collection. Included are early accession books, classed lists which employ the Richardson Call Number system, alphabetical and shelf lists, holding inventories, and gift acquisition records (known as DeLong lists, after their compiler). Also included in this subseries are several finding lists for the Princeton Theological Seminary Library collection. The volumes cover the acquisition of works; their disposition to various special libraries on campus; their use and circulation; and other miscellaneous topics related to the collections, or even to the Library itself (as in "Appraised Valuation of the Furnishing of the University Library, Princeton University, 1911").

The Shelf Lists, Accession Records, and Inventories series contains records that document the library's collections, primarily in ways that relate to the physical location of volumes on the library's shelves. The Shelf Lists group volumes together according to loosely formed topics. Although these lists are undated, they almost certainly refer to the shelves of the Pyne and Chancellor Green libraries. The Holdings Inventories fulfill a similar purpose, though for a later period when the classification system had become more complex. The DeLong Lists are lists of gifts to the library compiled by E. DeLong of the Acquisitions Department.

The Early Catalogs and Technical Records series consists of individually boxed volumes which document the Library's collection. The volumes cover the acquisition of works; their disposition to various special libraries on campus; their use and circulation; and other miscellaneous topics related to the collections, or even to the library itself (as in "Appraised Valuation of the Furnishing of the University Library, Princeton University, 1911").

October 2010 Accession, Cataloging Guides and Related Materials, 1884, 1964-1982 consists of instructional manuals, a subject catalogue of the library and a library brochure.

The Publications subseries includes books and exhibition catalogs that were published with the support of the Friends, as well as brochures and pamphlets regarding the Friends, and printed invitations to Friends'-sponsored events. The subseries also contains other Library and outside publications collected by the Friends.

Subseries 8B, Manuscripts Relating to the Rittenhouse Orrery consists of letters and documents tracing the search for and restoration of the orrery; exhibition plans, display cards, and publicity releases related to the 1954 exhibition of the orrery; photographs of the Rittenhouse and other orreries; two notebooks, containing a "Documentary History of the Rittenhouse Orrery, 1767-1951" and "18th Century Orreries Before and After David Rittenhouse," with bibliographies; and notes and typescripts for Howard C. Rice's "The Rittenhouse Orrery" (1954), a narrative commentary on the exhibition. Also included are photostats of manuscript material, including letters by Thomas Jefferson and David Rittenhouse, lent to the Library for the exhibition by Elizabeth Sergeant Abbot, and lists of items borrowed from other sources.

This subseries consists primarily of newspaper clippings and press releases on all matter of Library-related topics, and also contains narrative histories of the Princeton University Library.
