This copy of this US Government report was curated by Alex Wellerstein (added OCR'ed text and renamed PDFs). His description is here: General Groves’ secret history.The description below is from the original source website, Manhattan District History at the US Department of Energy's OpenNet.General Leslie Groves, head of the Manhattan Engineer District, in late 1944 commissioned a multi-volume history of the Manhattan Project called the Manhattan District History. Prepared by multiple authors under the general editorship of Gavin Hadden, a longtime civil employee of the Army Corps of Engineers, the classified history was "intended to describe, in simple terms, easily understood by the average reader, just what the Manhattan District did, and how, when, and where." The volumes record the Manhattan Project's activities and achievements in research, design, construction, operation, and administration, assembling a vast amount of information in a systematic, readily available form. The Manhattan District History contains extensive annotations, statistical tables, charts, engineering drawings, maps, photographs, and detailed indices. Only a handful of copies of the history were prepared. The Department of Energy's Office of History and Heritage Resources is custodian of one of these copies.The history is arranged in thirty-six volumes grouped in eight books. Some of the volumes were further divided into stand-alone chapters. Several of the volumes and stand-alone chapters were never security classified. Many of the volumes and chapters were declassified at various times and were available to the public on microfilm. Parts of approximately a third of the volumes remain classified.The Office of Classification and the Office of History and Heritage Resources, in collaboration with the Department's Office of Science and Technical Information, have made the full-text of the entire thirty-six volume Manhattan District History available on this OpenNet website. Unclassified and declassified volumes have been scanned and posted. Classified volumes were declassified in full or with redactions, i.e., still classified terms, phrases, sentences, and paragraphs were removed and the remaining unclassified parts made available to the public. All volumes have been posted.Following is a listing of the books, volumes, and stand-alone chapters of the Manhattan District History with links to pdf copies.Book I GeneralVolume 1 - GeneralVolume 1 - General Appendix E; General IndexVolumes 2 and 3 were not prepared by the Manhattan Engineer DistrictVolume 4 - Auxiliary ActivitiesChapter 1 - Legislative Contacts of Manhattan DistrictChapters 2 through Chapter 5 - Foundation of the National Laboratories (Ch. 2); Program for Production and distribution of radioisotopes (Ch. 3); Research and Development of Atomic Energy for Power (Ch. 4); and Declassification and Distribution of Project Information (Ch. 5)Chapter 6 - Investigation of the After Effects of the Bombing in JapanChapter 7 - Contributions of Representatives of the Manhattan District to the Discussions and Proposals for International ControlChapter 8 - Press Releases - Part 1Chapter 8 - Press Releases - Part 2Chapter 9 & 10 - Assistance on the Canadian Pile Project (Ch. 9); and the Oak Ridge Institute of Nuclear Studies (Ch. 10)Chapter 11 - Ames ProjectChapter 12 - Activities of the National Bureau of StandardsChapter 13 - Preparation and Publication of the Smyth ReportChapter 14 - Investigation of Miscellaneous Processes of Separation of Uranium IsotopesVolume 5 - Fiscal ProceduresVolume 5 - Fiscal Procedures AppendicesVolume 6 - Insurance Program and SupplementVolume 7 - Medical ProgramVolume 7 - Medical Program SupplementVolume 8 - PersonnelVolume 9 - Priorities ProgramVolume 10 - Land Acquisition CEWVolume 10 - Land Acquisition CEW AppendicesVolume 11 - Safety ProgramVolume 11 - Safety Program Appendix GVolume 12 - Clinton Engineer Work - Central FacilitiesVolume 12 - Clinton Engineer Work - Central Facilities Appendices A, B, & CVolume 12 - Clinton Engineer Work - Central Facilities Appendices DVolume 13 - PatentsVolume 14 - Intelligence & SecurityVolume 14 - Intelligence & Security- Supplement (w/Appendices)Volume 14 - Intelligence & Security - Foreign Intelligence Supplement No. 1Volume 14 - Intelligence & Security - Foreign Intelligence Supplements Nos. 2 & 3Volume 14 - Intelligence & Security - Top Secret Appendix to SupplementBook II Gaseous Diffusion (K-25) ProjectVolume 1 - General FeaturesVolume 2 - ResearchVolume 3 - DesignVolume 4 - ConstructionVolume 5 - OperationsVolume 5 - Operations - Supplement No. 1Volume 5 - Operations - AppendixBook III The P-9 ProjectBook IV Pile Project X-10Volume 1 - General FeaturesVolume 2 - Research Part I - Metallurgical LaboratoryVolume 2 - Research Part II - Clinton LaboratoriesVolume 2 - Research Part II - Clinton Laboratories - Top Secret AppendixVolume 3 - DesignVolume 3 - Design Appendices A, B, C, DVolume 4 - Land Acquisition, HEWVolume 4 - Land Acquisition, HEW Appendices A, B, C, D, EVolume 5 - ConstructionVolume 5 - Construction - Appendix AVolume 5 - Construction - Appendices B, C, D, & EVolume 6 - OperationVolume 6 - Operations - Appendix AVolume 6 - Operations - Appendices B, C, D, EVolume 6 - Operations - Top Secret AppendixBook V Electromagnetic ProjectVolume 1 - General FeaturesVolume 2 - ResearchVolume 3 - DesignVolume 4 - Silver ProgramVolume 5 - ConstructionVolume 6 - OperationBook VI Liquid Thermal Diffusion (S-50) Project - Secret SupplementBook VII Feed Materials, Special Procurement, and Geographical ExplorationVolume 1 - Feed Materials and Special ProcurementVolume 2 - Geographical ExplorationBook VIII Los Alamos Project (Y)Volume 1 - GeneralVolume 1 - General Appendices A, B, C, DVolume 1 - General Appendices E, FVolume 2 - TechnicalVolume 2 - Technical SupplementVolume 3 - Auxiliary ActivitiesChapter 1 - Los Angeles Procurement OfficeChapter 2 - Project CamelChapter 3 - Activities of Ohio State University Cryogenic LaboratoryChapter 4 - Dayton ProjectChapter 5 and 6 - Navy Participation (Ch. 5) and Sandia (Ch. 6)Chapter 7 - BoronChapter 8 - Operation CrossroadsChapter 9 - Supplementary Activities
