Theory of poetry

I bought a book recently. But unfortunately it is a hard copy. There was an excellent site called onestoppoetry which used to provide this kind of information. But now the site is taken down. There is another one called dversepoets.com. But somehow I don't find that as good as the onestoppoetry used to be.  

Today I found this nice website. Thought I will share with you
