A thousand copies of the report were printed by lithography at the Pentagon, and deposited in Groves's office in the New War Department Building in Washington, D.C., where they were kept securely locked away.
Final approval was sought from the President, Harry S. Truman, in a meeting at the White House on August 9, 1945, three days after the bombing of Hiroshima.
Stimson, Harrison, Groves, Conant, Vannevar Bush, and Fleet Admiral William D. Leahy presented their views, and Truman authorized the immediate release of the report.
The War Department released the thousand copies of the report that had been kept in Groves's office to the media for use by the radio broadcasters with an embargo time of 9:00 pm on August 11, 1945, and for the newspapers of August 12.

The original title of the report, before it was published in book form, was Nuclear Bombs: A General Account of the Development of Methods of Using Nuclear Energy for Military Purposes Under the Auspices of the United States Government, 1940–1945.
The word "nuclear" was changed to "atomic" because while the former was favored by physicists, it was not in common use by the general public at that time.
This was the title used on the copyright certificate.
The book was copyrighted to Smyth but issued with the statement that "reproduction in whole or in part is authorized and permitted".
Groves had the report copyrighted by Smyth in order to prevent someone else from copyrighting it.

Groves was concerned about the security implications of the title, so instead of having "Atomic Bombs" on the cover, it was left blank, and a rubber stamp was made.
The intention was for this to be used on each copy before it was distributed.
This was done for the copyright deposit copies, but not those given to the press or the public.
The lumbering subtitle therefore became the title.
A side effect of this was that it became generally known as the "Smyth Report".
Over the years, the term "nuclear" gradually gained traction, and by 1960 it had become more common than "atomic".

In mid-1945, Smyth approached Datus C. Smith, the director of Princeton University Press, about the possibility of renting his printing plant to the government during a two-week summer shutdown so that Smyth could produce 5,000 copies of a top secret report.
Smith's response was that he found it hard to imagine anyone needing to print 5,000 copies of a top secret report.
He found it much easier to imagine delays due to unexpected printing problems, and his workers returning from summer vacation to find themselves locked out of a plant filled with top secret material.
Under the circumstances, he felt that he could not risk this.

After the Smyth Report was officially released, Smith immediately offered to publish it.
Smyth patiently explained that anyone was free to publish it, but Princeton University Press was only willing to do so on the understanding that this would be "Smyth's edition".
Meanwhile, Smyth approached McGraw-Hill about publishing it.
The editors at McGraw-Hill found the manuscript dull and somewhat technical for a general audience and suggested a rewrite.
Smyth balked at this, as it would have meant going through the censorship process again.
James S. Thompson, the president of McGraw-Hill, pointed out the U.S. Government Printing Office would be putting out an edition, probably more cheaply than he could, and there would likely be little profit in a McGraw-Hill edition.
Smyth then turned back to Princeton University Press.
He had only one condition: that he receive no royalties.
Princeton University Press agreed, but added a stipulation of its own: that Groves's approval be secured.
Smyth obtained this in a letter dated August 25, 1945.

Princeton University Press received a copy of the typescript lithograph edition with hand corrections from Smyth on August 17, 1945.
The typographers had already started work from another copy.
Maple Press of York, Pennsylvania, was lined up to do the printing.
Because of wartime shortages, one of a publisher's biggest worries was finding adequate supplies of paper.
