David Collier is an independent investigative journalist whose work examines antisemitism, anti-Zionism, Islamic extremism, terrorism, media coverage and related issues in the UK and internationally. Through his website, he publishes investigative reports and commentary based on research, including examinations of public figures, organisations, political activity and historical narratives. His articles also critique reporting by broadcasters and other media outlets, and discuss antisemitism within religious institutions and on university campuses.

The site offers readers a range of written resources, including original reports, historical documents and book reviews, alongside regular articles and open letters. Recent work featured on the website includes a timeline examining Mohsen Mahdawi’s political activity and reporting on the Church of England, publishers and media coverage. Visitors can browse by topic, search the archive, and follow Collier through Facebook, Twitter and YouTube. The website also provides a way to donate in support of his independent research and writing. Together, these resources present Collier’s work as an investigative platform focused on documenting and challenging what he describes as antisemitism, anti-Zionism and revisionist narratives.
