"The Parallel History Project on Cooperative Security (PHP, the former Parallel History Project on NATO and the Warsaw Pact), provides new scholarly perspectives on contemporary international history by collecting, publishing, and interpreting formerly secret governmental documents. In response to the declassification of NATO records and the growing availability of documents from archives in Eastern and Central Europe, PHP as a cooperative undertaking of more than twenty partner institutes brings together leading Cold War historians, archivists, and government officials. The findings are presented to the specialist academic community at conferences and published both in print and on the PHP website. Since its establishment in 1999, the project has collected thousands of pages of material on security-related issues of the Cold War, published a large number of online documentaries and publications on central issues such as mutual threat perceptions and alliance management, and organized several major international conferences on war planning, intelligence, and intra-bloc tensions."
