One idea could be to get him tickets to a literary festival in his area or in a city that he's never been to before. Another idea could be to get him a signed copy of a book by one of his favorite authors who might be attending a festival he is interested in, if you know the author schedule. Alternatively, you could get him a nice bookshelf to display his collection of books from the festivals he's attended, or get him a special edition of his favorite book, such as a limited edition or one with illustrations. Lastly, you could buy him a subscription to a literary magazine, or a set of personalized bookmarks with his name engraved.
Or you can get him a star map with the date when he was born.
