You can put them in Hubs individually by typing them in or copying and pasting, if they are already in a document.
If you want them all on one page. Put them all on - may be a blog on Google or another blog - then put the URL link of it on your page. When people click on the link, it will open up to all your poems.
Ps. If you visit my profile and click on "Poems", it will be more clear what I'm trying to explain. Regards.
