How to remove a previously added ebook from a paper book page

[نزار]

Hello,
The book in question is my own first poetry book published back in 2007. I had uploaded the ebook version (PDF) to the book page (don't know how, because the feature doesn't seem to be available anymore or else I forgot how to do it.) Now, I want to remove that downloadable PDF because the ebook is available elsewhere in an updated edition. How can I do this? I can't find a way to delete the ebook alone and the only obvious way is to remove the whole book this losing the reviews and ratings.
Any ideas?
