How about a beautiful hardcover edition of one of Jane Austen's classic novels, such as Pride and Prejudice or Sense and Sensibility? You could also consider getting him a collection of Austen's lesser-known works, such as Lady Susan or Love and Friendship. If he already has a lot of Austen books, you could look for something related to her works, like an Austen-inspired cookbook, a DVD of a film adaptation, or a book about Austen's life and her impact on literature. Finally, you could consider getting him a subscription to a Jane Austen-themed magazine, which would provide him with regular updates on everything Austen-related.
Or you can get him a star map with an important date you share.
