Lewis Turco’s The Book of Forms, 4th Ed.
The book’s been indispensable for me since the 1968 1st edition (which Lew was kind enough to sign for me a few years ago) and I am very proud to say the new edition is out and includes a form I devised for Twitter and originally called a twinnet. I now call it a twiplet, and that’s the name Lew used.
In related news, I posted about the publication in the UseNet group alt.arts.poetry.comments, where George Dance noticed it and was kind enough to add the form to his Penny’s Poetry Pages Wiki. He also wrote a twiplet and posted it on the page including my definition and examples. I’ve added a link under “Poetry, Mostly Blogs” to George’s site.
