A personalized book embosser could be a great gift for your wife. It would allow her to personalize and mark her books in a unique and elegant way. You could also consider getting her a bookshelf or storage system that will help to neatly organize and display her collection. Alternatively, a gift card to her favorite bookstore or a book subscription service could be a great way to support her love for collecting books. If there is a particular book or author she is interested in, you can also consider buying a rare or signed edition of that book.
Or you can get her a star map with an important date you share.
