There are many "old" books that are known by different titles. For example, La Mule sans frein (English: The Mule Without a Bridle), which is also known as La Demoiselle à la mule (English: The Damsel with the Mule). And some books are known by 3, 4, or even more titles.
Such a variety of titles of the same books makes it difficult to choose the right one to use it in a bibliography. Is there a website where I can (at least!) search for an arbitrary book and then see a complete list of its titles?
