Scope and Contents
The Instrument category covers devices and tools used in arts and sciences, including but not limited to architecture, biology, medicine, geography, physics, chemistry and related laboratory investigation, navigation, in industry with machinery, astronomy, and a variety of optics including reading glasses. An emphasis on engineering and survey work is evident in the volume of Drawing and Surveying catalogues present.
Materials include a small sampling of business records, particular invoices and receipts, with also some advertisement, correspondence, financials, import/export documents. The bulk of material is comprised of product catalogues, many with detailed descriptions, specifications, and illustrations, plus pricing information. A number of catalogues are in German. A small portion of the catalogues are not instruments per se, but are accompaniments used with instruments. For example, specimen slides for microscopes. A few company publications are present as well. Several guides on the use of or history of some apparatus are present, as are a few stand-alone illustrations, though most catalogues are heavily illustrated.
No extensive runs or complete records exist for any single company, brand, and no particular depth is present for any singular subtopic though some publications may provide general and historical overviews of a person, company, or facet of industry. Separate folders were used for a few companies which have a small bulk of material. Companies of note: Bausch & Lomb, Sperry Corporation and Wheelco Instrument Company.
With the industries and trades represented in this category, there is overlap with Hardware, Tools, and Mensuration.
