Scope and ContentDrawing Instruments and Materials for High Schools, Preparatory Schools and Manual Training Schools. Published by Keuffel & Esser Co., New York & Hoboken, 1936. Booklet, 5-3/4" wide x 8-3/4" high. pp. iv, 117, illustrated. Unpriced. Lacking: separately issued price list. Page iii: "In this catalogue are illustrated and described Drawing Instruments, Drawing and Tracing Papers, Slide Rules, etc., which are of particular interest to instructors and students of mechanical drawing in High Schools and Vocational Schools. Many of the materials listed here also appear in the 38th edition General Catalogue. Those designated by catalog numbers high than 8000, however, are shown only in this booklet, and are intended primarily for school use. They are of good quality, but do not have the refinements of similar articles designed for professional use." Page [ii] is the copyright page and lists several dates which may be useful as dates that the school catalogues were issued: 1901, 1904, 1906, 1909, 1913, 1921, 1924, 1926, 1929, 1933, 1934, 1936. While some of these dates coincide with the edition dates for the General Catalog, not all do so.
