Clavics is listed as a bestseller for the London Review Bookshop (newsletter of April 28th).
The book was reviewd in The Economist (first time that's happened for a book of poetry by Hill).
For more breadth, why not listen to Hill's first and second Oxford Professor of Poetry lectures on-line?
He'll be speaking again, on "Poetry and Disproportion" in Oxford, on May 10th, at 5:30 p.m. in the South School of the Examination Schools.
