How can one rate an anthology of poems chosen by collective voting, really? It seems well-intentioned, the preface thankfully includes an excellent modern poem which didn't make the list, and the editor's synopsis is (thankfully?) short of analysis.
My edition is simply hard to read based on the book layout. I've also read that some of the longer poems were cut down on the sly. Finally, what can one say about a nation which puts "Toilet" at number 79 of the 100 greatest works in its own language?
Better, longer and internationally agreed upon lists are readily available online too.
