The APT Bulletin, published three times per year by the Association for Preservation Technology International (APT), provides state-of-the-art technical information in the field of historic preservation. Articles published in the Bulletin showcase cutting-edge preservation techniques, as well as innovative applications of established restoration technologies. Articles also include case studies demonstrating best practices, exemplary craftsmanship, debates on preservation philosophy, and histories of building materials, technologies, and systems. The APT Bulletin also addresses emerging issues and trends, such as preservation engineering and the integration of sustainability and preservation. Many of the articles published in the APT Bulletin each year are developed from papers presented at the annual APT conference or other APT-sponsored events and symposia.

The Association for Preservation Technology International (APT) is a multi-disciplinary membership organization dedicated to promoting the principles, techniques, and technology necessary for conserving historic structures and their settings. APT's members, who hail from more than thirty countries, include architects, engineers, conservators, consultants, contractors, craftspersons, curators, preservationists, developers, educators, historians, landscape architects, technicians, students, and other persons directly involved in the application of methods and materials to maintain, conserve, and protect historic structures and sites for future use and appreciation. The international, interdisciplinary character of APT--with its publications, conferences, training courses, awards, student scholarships, regional chapters, and technical committees--makes it the premier world-wide network for anyone involved in the field of historic preservation.
