Missing key classical/famous poems

This app is such a great idea! But it seems to be pretty incomplete e.g. Famous poems missing like Stopping by the Woods on a Snowy Evening by Frost and The Tiger by Blake, and point taken about lack of diversity of poets (lots of white folks!). I understand the challenges of needing the poems to be in the public domain or have mobile rights, but the two I cited are easily findable in the Internet and Id expect Blake at least to be in the public domain.
