This was an essential book that I needed for Literature therefore it was necessary for me to buy it, however, there are a lot of poems in there which aren't studied at AS Level so it would have been easier just for me to buy the Selected Poems by Carol Ann Duffy, however no-where sells them anymore. So, in case anyone had my problem, this includes all the poems and extra ones from Selected Poems (as my teacher told me to buy Selected Poems, and I took ages trying to find that book, because it was not being published anymore). However, some of the poems have been alterned slightly in the way there placement; where some of them contained enjambment in the original poem, in this book, it has eliminated the enjambment, which could be part of one's analysis on structure of the writing.
All in all, this book does contain the poems I need, which is the most important thing, but the quality of the cover is not as good as Selected Poems. Especially if you are using it constantly, the edges of the pages do start to deteriorate in quality, which is why I have given four star on this book of poems.
