'When people say ‘difficult’ and ‘poetry’ in the same sentence they are usually referring to the experience of reading a certain type of poem. It is often a poem that seems to make little sense, that doesn’t have a strong sense of narrative, that uses strange words or strange forms, that does not follow rules of grammar and syntax, that may not even communicate any coherent message at all. Difficult poetry, for some reason, is a phrase that refers to these weird poems and the people who try to read them. Difficult poetry is about the tension and struggle to make sense of this weirdness.' (Oscar Schwartz and Holly Isemonger : Introduction)
