Scribd has been removing a lot of romances. It might be a good idea for Scribd subscribers to keep an eye on books that are expiring.
One step Scribd has taken is to remove books from search results. Some books are still there but can't be found.
To see if a book still exists but is hidden, you can use an outside search engine.
Googling will give you the links. Clicking on author names also won't show the books that are still there. If a book is marked as unavailable, then you're out of luck.
