William Tutte's manuscript notebook from his time as a student at Trinity College Cambridge. Manuscript includes graphs and formulas regarding the Four colour theorem or the Four colour map theorem (considered the central problem in graph theory). Notebook includes a folder with annotations made by Tutte referring to the content and pages with his annotations divided into twelve sections.

Fonds consists of material relating to William Kindree's involvement in the WATFOR 360 group and material relating to the 25th anniversary of WATFOR. Includes Kindree's notes (design and general) and draft documentation, guides and other publications about WATFOR, photocopied conference proceedings and published papers, correspondence, a newsletter, and a photograph of the WATFOR team.

Three notebooks kept by Thomas P. Stowell with mathematical problems, solutions, and notes.

Materials used or accumulated by Robert "Bob" Hanselman during his time as a student at the University of Waterloo. Includes photographs of the University's first buildings, a slide rule, a book with mathematical tables used by Hanselman in his courses, two yearbooks, and Hanselman's briefcase.

One manuscript copy (1 vol. 348 pp.) of Lorenzo Mascheroni's Geometrical problems resolved by means of compasses or by the mere description of circles translated and with additions by A.B. Lousada, Devonshire, 1820. Also includes bound in original plates with diagrams.

One manuscript copy (1 vol. 347 pp.) of Euclid's elements of geometry being an abbreviation of Mr. Cunn's edition of the 1st, 2nd, 3rd, 4th, 5th, 6th, 11th and 12th books in which the verbal demonstrations are greatly abridged and the figures for their elucidation laid down with accuracy, so as to be proved by scale and compass, by James Horne, son of Richard Horne, First Clerk of the Admiralty. Two bookplates, one of W.R.B. Osterholt and one of Henry Buxton Forman.

The nucleus of this collection, begun by the University of Waterloo's first dean of Graduate Studies, Dr. R. Stanton and the University's first librarian, Mrs. Doris Lewis, during the 1960's, is 45 editions of Euclid's Elements of Geometry The collection has continued to be developed as a special collection. A collection of 110 nineteenth century mathematics books was acquired in 1981.

The earliest edition of Euclid's Elements of Geometry is dated 1505. The collection includes the first translation of the Elements into a modern language (1543), the first English language edition (1570), the Byrne edition, using coloured printing (Pickering, 1847), and the first edition printed in France (1516).

The collection includes 9 of the 46 editions listed by Thomas-Stanford in his Early Editions of Euclid's Elements (which lists editions published prior to 1600), some of which are of "great rarity" according to Thomas-Stanford. The collection is particularly useful in showing the transmission and teaching of the Elements from almost the earliest printed form to modern texts. Unusual methods of presenting geometry are represented in books with movable stand-up diagrams from the sixteenth and eighteenth centuries, and the "Pickering Euclid" of 1847, which uses colours rather than letters to describe theorems.

Holograph manuscript titled "Cours de calcul integral" by Auguste Bienaimé Désiré Pioch (1812-1846). Bound with his "Memoire sur les fonctions arbitraires exprimes par des integrales doubles" [G3145]. Taken from Tome XV of Memoires Couronnes, Academie Royale de Bruxelles.
