The American Religion: The Emergence of the Post-Christian Nation (1992; second edition 2006) is a book by literary critic Harold Bloom, in which he covers the topic of religion in the United States from a perspective which he calls "religious criticism".
 Religious denominations Bloom discusses include The Church of Jesus Christ of Latter-day Saints, Christian Science, the Seventh-day Adventist Church, Jehovah's Witnesses, and the Southern Baptist Convention.
School of Resentment is a term coined by critic Harold Bloom to describe related schools of literary criticism which have gained prominence in academia since the 1970s and which Bloom contends are preoccupied with political and social activism at the expense of aesthetic values.

 He is Phyllis Fay Horton Distinguished Service Professor Emeritus in the Humanities and in English Language & Literature, Comparative Literature, and the College at the University of Chicago, where he has taught since 1967, as well as chair of Theatre and Performance Studies.
 "One of the most learned and devoted of Shakespeareans," so called by Harold Bloom, he specializes in British drama of the Renaissance, and has edited and introduced the complete works of William Shakespeare in both the 29-volume, Bantam Classics paperback editions and the single-volume Longman edition.
 Bevington remains the only living scholar to have personally edited Shakespeare's complete corpus.
The Flight to Lucifer is a 1979 book by the American literary critic Harold Bloom.
 His only novel, it was composed as a sequel to the David Lindsay 1920 novel "A Voyage to Arcturus", which supplied the concept of a voyage through space to a distant planet created by a demiurge, and a few other incidental features of the book.
 However, most of its content derives fairly directly from Gnosticism, which Bloom had studied.

Harold Hart Crane (July 21, 1899 – April 27, 1932) was an American poet.
 Finding both inspiration and provocation in the poetry of T. S. Eliot, Crane wrote modernist poetry that was difficult, highly stylized, and ambitious in its scope.
 In his most ambitious work, "The Bridge", Crane sought to write an epic poem, in the vein of "The Waste Land", that expressed a more optimistic view of modern, urban culture than the one that he found in Eliot's work.
 In the years following his suicide at the age of 32, Crane has been hailed by playwrights, poets, and literary critics alike (including Robert Lowell, Derek Walcott, Tennessee Williams, and Harold Bloom), as being one of the most influential poets of his generation.
The Anxiety of Influence: A Theory of Poetry is a 1973 book by Harold Bloom.
 It was the first in a series of books that advanced a new "revisionary" or antithetical approach to literary criticism.
 Bloom's central thesis is that poets are hindered in their creative process by the ambiguous relationship they necessarily maintained with precursor poets.
 While admitting the influence of extraliterary experience on every poet, he argues that "the poet in a poet" is inspired to write by reading another poet's poetry and will tend to produce work that is in danger of being derivative of existing poetry, and, therefore, weak.
 Because poets historically emphasize an original poetic vision in order to guarantee their survival into posterity (i.e., to guarantee that future readers will not allow them to be forgotten), the influence of precursor poets inspires a sense of anxiety in living poets.
 Thus Bloom attempts to work out the process by which the small minority of 'strong' poets manage to create original work in spite of the pressure of influence.
 Such an "agon", Bloom argues, depends on six revisionary ratios, which reflect Freudian and quasi-Freudian defense mechanisms, as well as the tropes of classical rhetoric.
