Building Technology Heritage Library Reaches 10,000 Documents Milestone
The Building Technology Heritage Library (BTHL) is a project of the Association for Preservation Technology (APT) and is hosted by the Internet Archive. The 10,000th document was a 1904 tile, terra cotta, and fireplace catalog from a French Company: Emile Muller & Cie. This document is from the collection of Prof. Miles Lewis of Melbourne Australia, the latest of several private libraries that have been added to this increasingly international archive. Mike Jackson, the co-chair of this project said, “This product catalog is a perfect example of the wonderful resources APT is making available to the public. It is a beautifully illustrated and comprehensive overview of ceramic tile and architectural terra cotta available in turn-of-the-century France. This is also a rare document that could only be found in a couple of research libraries and is now available to everyone.”
Why is this being done?
The Association for Preservation Technology recognized the value of period trade catalogs and other technical publications as a primary research tool for its members. There were only a few institutional collections of these materials, which made them difficult to access. APT saw great benefit to a comprehensive online digital archive to serve a broad audience of preservation practitioners, advocates, historians and students. These materials are in the pubic domain and made available to the public at no charge. The scope of the collection ends in 1963 as materials after this date are still under copyright protection.
Where do these materials come from?
These documents come from various library, museum and private collections. The Canadian Centre for Architecture (CCA) (www.cca.qu.ca) was the first major contributor. Two other major institutional libraries that have partnered with APT are the Southeast Architectural Archive at Tulane University and the Avery Library at Columbia University. The BTHL has also digitized numerous documents from private collectors. Two examples include the paint catalogs from the collection of conservator Jablonski Building Conservation and the house plan catalogs from the collection of Wisconsin State Historic Preservation Officer James Draeger.
How are these materials being used?
“The Building Technology Heritage Library is an invaluable resource for researchers and practitioners alike. It is the go-to source for primary resource material related to building technology. APT was wise to invest the time into creating this valuable collection and we are grateful to our initial stakeholders: the Canadian Centre for Architecture, the Historic Preservation Education Foundation, the National Center for Preservation Technology and Training and the Richard H. Driehaus Foundation.” ~Anne Sullivan, School of the Art Institute, Chicago
A few comments from users:
Subject: Pyrobar rehab “This library is an invaluable resource. Working on a seven story 1923 building in West Virginia I was asked by the architect what this material was surrounding the elevator shaft. I told him it was Pyrobar and provided the US Gypsum Catalog scan showing that it had a two-hour rating. He used this as documentation for the fire marshal. It saved the project the cost of removal of the material and constructing a modern two-hour fire rated drywall wall. They were appreciative to say the least.”
Subject: Serendipity! “I was reviewing a terra cotta question with someone in the office, so of course turned to the BTHL. In scrolling through quickly to find a good example to illustrate our conversation, I happened to see a photo of another terra cotta building that we were working on at the time! This serendipity was so lovely, and of course, so helpful!”
