There was once a genre with no name: Poetical types and whence they came

There has been little research into poetry classification and the potential to access poems by form and genre. The categories listed in the Library of Congress Genre/Form Terms (LCGFT), Wikipedia, Amazon.com, and the poetry-sharing platform, PoetrySoup, were compared through a systematic mapping process. It was found that LCGFT coverage is more extensive for poetry than fiction, but all four sources’ coverage is limited. Beyond a small core of well-established forms and genres, poetry is classified in many less well-known ways, with many categories based on form, as well as a wide range of other characteristics, including some very specific ones.
