APT Building Technology Heritage Library

Posted by: Sarah Ripple on Thursday, March 8, 2018 at 12:00:00 am

The APT Building Technology Heritage Library (BTHL) reached another milestone in March 2018 when the three millionth documents was viewed.  This year there has been an uptick in regular users to more than 2,000 documents a day. The Internet Archive has also started to share data about the location of users and there has been a noteworthy increase in international users.  The most US visitors come from the most populous states of California, New York, Ohio and Illinois.  If you are an APT user, please be sure complete the online review and tells us why a particular document was useful.

The growth of the BTHL in content and viewers continues to show the value of this project as an APT initiative.  From its small start in 2016, the online collection has grown to more than 9,500 documents showcasing a wide range of building materials, assemblies and technical data.  Thanks again to our major sponsors,  the Richard H. Driehaus Foundation, Historic Preservation Education Foundation, Illinois Historic Preservation Agency and the National Center for Preservation Technology and Training.


As an APT active member how can I access some of the historic technical catalogs in this collection to use as reference material?

Welcome to the APT Blog

"It has been said that, at its best, preservation engages the past in a conversation with the present over a mutual concern for the future."
- William Murtagh, Keeping Time: The History and Theory of Preservation in America

In our increasingly digital age, the face and form of this conversation is transforming. Social media has become a driving and influential force in every aspect of our lives: politics, community, religion, entertainment. It should be no surprise that the preservation field is wholeheartedly embracing social media outlets. A quick internet search of something as simple as "historic preservation blog" resulted in more than 86,000 results.

The Association for Preservation Technology International is pleased to add our voices to this new conversation.

For over forty years, APT has been a leader in preservation technology, providing not only education and technical training opportunities but also providing a social venue for the sharing of experience and knowledge. This blog is a new approach to hosting our part of the conversation between the past and the present, developed around a user-generated dialogue and aimed at promoting interaction and participation.
