As you read this, writers, publishers, designers and enthusiasts of chapbooks (booklets of prose or poetry) are gathering in New York City for the 2012 Chapbook Festival. This three-year-old affair features a book sale, panel discussions and workshops over several days. But the founder of one major industry publisher, Ugly Duckling Presse, won't be there. That's because Matvei Yankelevich is here, working with Colorado College students on letterpress printing and overseeing The Chapbook in the 21st Century: Efficiency/Excess/Ephemerality, an exhibit at Coburn Gallery (902 N. Cascade Ave., theideaspace.com). It kicks off today with an opening reception from 4:30 to 6 and runs through April 17. — Edie Adelstein
