The Urantia Book (sometimes called The Urantia Papers or The Fifth Epochal Revelation) is a spiritual, philosophical, and religious book that originated in Chicago, Illinois, United States sometime between 1924 and 1955, claimed, when first published, to have been written by celestial beings. The actual authorship remains a matter of debate, though it has been noted that it appears to have plagiarized multiple sources, without attribution. It received various degrees of interest ranging from praise to criticism for its religious and science-related content, its unusual length, and the unusual names and origins of the authors named within the book.The Urantia Foundation, a U.S.-based non-profit group, first published The Urantia Book in 1955. In 2001, a jury found that the English-language book's copyright was no longer valid in the United States after 1983. Therefore, the English text of the book became a public domain work in the United States,[6] and in 2006 the international copyright expired.The exact circumstances of the origin of The Urantia Book are unknown. The book and its publishers do not name a human author. Instead, it is written as if directly presented by numerous celestial beings appointed to the task of providing an "epochal" religious revelation
