Curious George Visits the Library is a children's book by Margret and H.A. Rey where the inquisitive monkey's first trip to the library turns chaotic as he tries to gather all the books he wants, leading to a comical mess that is cleaned up with help from the librarian and other children, and he earns his own library card. The book celebrates reading and includes interactive elements like library tips, a maze, and a bookmark in some editions, with bilingual versions also available.
