My guess is that poetry pamphlets celebrate the visual impact of poetry in a way stripped down words posted on blank blog space (as I do) can’t match. They certainly add an element to the enjoyment of new poetry. The Guardian blog post is last year’s, but the contest it concludes with is open again (see British Library for details–British published only, I think). It makes me consider the presentation of my poems, the intersection of the visual and the verbal.
