However, I gave it "Jane Eyre" (a mid-19th century novel by Charlotte Bronte; it's a classic) with the expectation that it will return "Wuthering Heights" – another a classic novel written in mid-19th century by Emily Bronte (yes the authors are related) – among other things. People who like Jane Eyre tend to like Wuthering Heights, and vice versa.
But everything it returned were new works – published in the last 20 years – of stories that are set in the 19th century.
The only filters applied were: "Preferred: Gothic romance novel, Victorian literature, Highly influential classic literature, Early 19th-century England ".
So, something seems amiss for now. Nevertheless, it's a very cool idea.
(Edited to fix my grammar; English is not my first language, so pardon me for any mistakes.)
