Andrew Joron came up with the term to describe his science-fiction poetry. An apt term to describe the project a. rawlings and I are currently conducting (previously described as "archeography," until a. informed me it meant something else)(on the other hand, our collaboration also falls under the influence of 'pataphysics). Other poets whose work also falls the "speculative lyric" label? Joron, in his book Cry to Zero (an essay from which has been excerpted in the latest issue of Parthenon West Review) mentions Robert Duncan. I can also think of Christine Hume's Alaskaphrenia, Johannes, Aase Berg.
