| Plan Net |
| Preservation Trades Network - PTN was conceived in 1995 at an Association for Preservation Technology (APT) conference roundtable strategy session in Washington, DC. At the time, representatives of the preservation trades felt it important for the preservation trades to be recognized as a valued member of preservation project teams. To do this, the preservation trades took action to build a community of like-minded individuals who share knowledge of the process of historic preservation as it occurs in the field. PTN was formed to provide a focus on and support of the sharing of the preservation trade's knowledge of the physical process of preservation, of how to shape and work historic materials. From this beginning PTN became a Task Force of APT. |
