Final answer:
Gilderoy Lockhart is a character from the Harry Potter series known for books like "Wandering with Werewolves," but "Magical Maladies and Their Cures" and "The Dark Arts: A Complete Guide" are not his works. "The History of Quidditch" exists in the wizarding world but is not authored by Lockhart.
Step-by-step explanation:
Gilderoy Lockhart is known for many books he has supposedly written, famed within the Harry Potter series. Among the published works attributed to him are "Wandering with Werewolves", as well as others with similarly alliterative and adventurous titles. However, "Magical Maladies and Their Cures" and "The Dark Arts: A Complete Guide" are not listed among his works in the series. "The History of Quidditch" is a book that exists within the wizarding world, but it is not written by Lockhart. Instead, Lockhart's books are primarily focused on his supposed exploits and encounters with magical creatures and situations.
Lockhart's books, though widely read in the wizarding community, are later revealed to be fabrications. He claimed the achievements of other wizards as his own to gain fame and fortune. His works, though fictional within a fictional world, resonate with themes seen across children's literature, where fantastical elements and the supernatural often play a significant role.
