Xanaduism

“[Xanaduism is] academic research that focuses on the sources behind imaginative works of literature and fantasy. John Livingstone Lowes, in his publication The Road to Xanadu (1927), inspired the name, which in turn goes back to Coleridge’s visionary poem ‘Kubla Khan’. . . . More recently, the term has been used in a pejorative sense to describe scholarship involving dubious scrutiny of amorphous, difficult-to-prove sources, especially simplistic studies lacking any redeeming theoretical perspectives.”
