This incomplete collection is composed of historical materials donated by the CMU Department of Mathematics in 2024 and department materials previously housed in the CMU Vertical Files collection. The collection includes departmental meeting minutes, correspondence, including some with CMU President Charles L. Anspach, brochures, fliers, posters, publications, including New Letters with a note from CMU President Eugene C. Warriner, clippings, photographs, and images printed from CDs, documenting staff, students, and award winners, and mathematics conferences and students events held at CMU. The collection is organized alphabetically and chronologically and is in good physical condition.

Processing Note: 1.25 cubic feet of the collection was withdrawn during processing, mostly duplicates and inaccessible storage media, such as floppy and hard discs, cassettes, and zip drives. Acidic correspondence was photocopied and the copies were retained in the collection. A few CMU college-level fliers were added to the CMU Vertical Files and two issues of two serials were cataloged.

Leo Engleman worked trigonometric and surveying exercises in this cypher book from 1847 to 1848, possibly while a thirteen-year-old boy living in Pennsylvania. Many of the exercises include mathematical drawings and illustrations, and surveying examples often include additional features done in pencil and watercolor.

Many of the exercises include mathematical drawings and illustrations, and surveying examples often include additional features done in pencil and watercolor, such as trees, rivers, buildings, and lighthouses. A number of headings also feature watercolor embellishments and abstract or geometric designs, and the final pages of the volume include full-page watercolor designs of geometric shapes and a rose bush.

This cypher book contains mathematics problems and exercises copied and completed by Samuel Burrier. The sections include multiplication, addition, division, weights (apothecary weights, et al.), and liquid measures. Several of the headers incorporate chickens into the calligraphic lettering.
