I don t know the poet articles you speak of so I don t know what might be different with them but the rule as I understand it is that poetry should be quoted only as an integrated part of the article s discussion For example it is not sufficient to say Here is a poem by Bhupi Sherchan but it might be appropriate to say One of the characteristics of Bhupi Sherchan s style is such and such as can be seen in these verses from poem There was also another consideration which I didn t mention in my edit reason because I thought perhaps it was too obvious This is the English language Wikipedia and there is an expectation that English language readers can read any article without missing something because it s in another language That doesn t necessarily mean you can t quote from another language at all but if you do it should be accompanied by a suitable translation into English
