Four folders of notes by Frank Mallalieu of D. & H. Mallalieu, Bailey Mill, Delph, Oldham, Lancashire, compiled while studying in the Department of Textiles Industries, Huddersfield Technical College, including graph patterns and cloth swatches.

These items not only constitute survivals from one of the leading Lancashire textile manufacturers, in an era when the industry in that area was world-renowned, but also of what was considered to be one of the very best of the north of England's celebrated working men's colleges. A total of 507pp., 4to., in four folders. In addition to Frank Mallalieu's meticulous course notes, diagrams and calculations (with occasional tutors' markings), the contents include 99pp. of mimeographed course notes and 47 swatches of material. The four folders are coloured in either pink, blue or orange, each with the printed legend of Huddersfield Technical College and the details of the subject, stage, name and session written out in manuscript. The contents are complete and neatly presented, on aged and spotted paper, in heavily-worn covers, with a pervasive musty smell.
