Before Manroot 10 (1974/1975), the Black Sparrow Collected Spicer (1975), and Boundary 2 (1977), there was Caterpillar 12, edited by Clayton Eshelman, in July 1970.
Speaking for my own personal knowledge of Spicer publications, there is only static from 1977 to 1998.
In 1998, The House that Jack Built and Poet Be Like God were published.
Then in April 1999 came the Jack Spicer Issue of Jacket Magazine on http://www.jacketmagazine.com/.
Finally in November 2008, The Collected Poems of Jack Spicer was published by Wesleyan University Press.
About five years ago, I read Caterpillar 12, then quickly followed up with the issue of Jacket, Poet Be Like God, and The House That Jack Built. In 2009, I read My Vocabulary Did This To Me and boundary 2.
The year ended by acquiring and, in a manner of speaking, re-reading Billy The Kid (1959), The Holy Grail (1962), Language (1965), and Book of Magazine Verse (1966). But like my recently acquired copy of Dear Ferlinghetti (1964), I read them all for the first time.
I have been wondering lately how I got from there to here, and, more importantly, how did Spicer.
