The Holocaust History Project
（重定向自THHP）
The Holocaust History Project (THHP) is an inactive non-profit corporation based in San Antonio, Texas. Its archived website offers a comprehensive selection of documents, recordings, photographs, and essays regarding the Holocaust, Holocaust denial, and antisemitism. The project became known for its refutations of the Leuchter report and the Rudolf report. It has since assisted in the defense in the case of Irving v. Lipstadt. As of 2016 THHP website is no longer available online although its entire content is accessible via several hundred captures in the Internet Archives.
