Boon is a 1915 work of literary satire by H. G. Wells. It purports, however, to be by the fictional character Reginald Bliss, and for some time after publication Wells denied authorship. Boon is best known for its part in Wells's debate on the nature of literature with Henry James, who is caricatured in the book. But in Boon Wells also mocks himself, calling into question and ridiculing a notion he held dear—that of humanity's collective consciousness.

First and Last Things is a 1908 work of philosophy by H. G. Wells setting forth his beliefs in four "books" entitled "Metaphysics," "Of Belief," "Of General Conduct," and "Some Personal Things." Parts of the book were published in the Independent Magazine in July and August 1908. Wells revised the book extensively in 1917, in response to his religious conversion, but later published a further revision in 1929 that restored much of the book to its earlier form. Its main intellectual influences are Darwinism and certain German thinkers Wells had read, such as August Weismann. The pragmatism of William James, who had become a friend of Wells, was also an influence.

Floor Games is a book published in 1911 by H. G. Wells. This light-hearted volume argues in a humorously dictatorial tone that "The jolliest indoor games for boys and girls demand a floor." Illustrated with photographs and drawings, it briefly describes a number of games that can be played on "well lit and airy" floors with "four main groups" of toys: soldiers about two inches high, largish wooden bricks, boards and planks, and electric railway rolling stock and rails. Various remarks show that the book is based on Wells's experience of playing such games with his two sons, George Philip "Gip" Wells (1901-1985) and Frank Richard Wells (1903-1982), identified here only by their initials at their family home, 17 Church Row, in the north west London district of Hampstead.

The Story of a Great Schoolmaster is a 1924 biography of Frederick William Sanderson (1857–1922) by H. G. Wells. It is the only biography Wells wrote. Sanderson was a personal friend, having met Wells in 1914 when his sons George Philip ('Gip'), born in 1901, and Frank Richard, born in 1903, became pupils at Oundle School, of which Sanderson was headmaster from 1892 to 1922. After Sanderson died while giving a lecture at University College London at which he was introduced by Wells, the famous author agreed to help produce a biography to raise money for the school. But in December 1922, after disagreements emerged with Sanderson's widow about his approach to the subject, Wells withdrew from the official biography and published his own work separately.

Travels of a Republican Radical in Search of Hot Water is a collection of essays by H.G. Wells written in 1939. It is best known for the following description:A bush fire is not an orderly invader, but a guerrilla. It advances by rushes, by little venomous tongues of fire in the grass; it spreads by sparks burning leaves and bark. Its front is miles deep. It is here, it is there, like a swarm of venomous wasps. It shams dead and stabs you in the back. It encircles you so that there is no sure line of flight for its intended victims. It destroys bridges in your rear. It bars the road with blazing trees.

War and the Future (1917) is a work of war propaganda by H. G. Wells that was published in North America under the title Italy, France, and Britain at War. Wells would have preferred the title The War of Ideas, but his publisher over-ruled him. Except for the opening piece, its chapters were published as articles in the press. Though proclaiming early in the volume that "I avow myself an extreme Pacifist," Wells staunchly supported Britain's war against Germany "in the hope that so we and the world may be freed from the German will-to-power and all its humiliating and disgusting consequences henceforth for ever."

The Way the World is Going is a 1928 nonfiction book written by British author H. G. Wells.

The Work, Wealth and Happiness of Mankind by H. G. Wells is the final work of a trilogy of which the first volumes were The Outline of History (1919–1920) and The Science of Life (1929). Wells conceived of the three parts of his trilogy as, respectively, "a survey of history, of the science of life, and of existing conditions." Intended as an unprecedented "picture of all mankind to-day" in all its manifold activities, he called it "the least finished work . . . because it is the most novel." He hoped the volumes would play a role in the open conspiracy to establish a progressive world government that he had been promoting since the mid-1920s.

World Brain is a collection of essays and addresses by the English science fiction pioneer, social reformer, evolutionary biologist and historian H. G. Wells, dating from the period of 1936–1938.
