Book excerpt: Poetry criticism is a subject central to the study of literature. However, it is laden with technical terms that, to the beginning student, can be both intimidating and confusing. Philip Hobsbaum provides a welcome remedy, illuminating terms ranging from the iambus to the bob-wheel stanza, and forms from the Spenserian sonnet to modern 'rap', with clarity and comprehensiveness. It is an essential guide through the terminology which will be invaluable reading for undergraduates new to the subject.
