Pretty hard. There is no centralized book registry.
All you need to publish a book is a valid ISBN10/EAN13. You can buy those online in bulk. And technically you don't need one, but generally if you want to sell it enmasse you want one.
Given its owned by Amazon you'd think they'd limit it to known ASINs but then I guess they can't account for rare or old books that predate the isbn system.
