DESCRIPTION

The Building Technology Heritage Library (BTHL) is primarily a collection of American and Canadian, pre-1964 architectural trade catalogs, house plan books and technical building guides. Trade catalogs are an important primary source to document past design and construction practices. These materials can aid in the preservation and conservation of older structures as well as other research goals.

About the Building Technology Heritage Library

The BTHL contains materials from various private and institutional collections. These materials are rarely available in most architectural and professional libraries. The first major architectural trade catalog collection is that of the Canadian Centre for Architecture, which encompasses more that 4,000 catalogs from the early 19th century through 1963. In addition to the architectural trade catalogs, the initial contributions include a large number of house plan catalogs, which will be of great interest to owners of older homes. The future growth of the Building Technology Heritage Library will also include contemporary materials on building conservation.

Searching the collection

The BTHL keywords include the standard subject headings used by the Library of Congress and an additional nomenclature used by the Construction Specifications Institute (CSI). The CSI Master Format 2004 Numbers and Titles have been used for most materials. This will allow contemporary practitioners to search through historic archives with a modern nomenclature.
