Sixty-eight years ago, an atomic bomb was detonated on an isolated corner of southern New Mexico in a weapon test named Trinity.

This month,  The Manhattan Project: Resources, a web-based, joint collaboration between the Department’s Office of Classification and Office of History and Heritage Resources has been launched. The site is designed to disseminate information and documentation on the Manhattan Project to a broad audience including scholars, students, and the general public. OSTI is hosting this information as part of the OpenNet web site. Manhattan Project Resources consists of two parts: 1) a multi-page, easy to read and navigate Manhattan Project: An Interactive History providing a comprehensive overview of the Manhattan Project, and 2) the full-text, declassified, multi-volume Manhattan District History commissioned by General Leslie Groves in late 1944. The new site brings together an enormous amount of material, much of it never before released.
