How about a set of signed first edition J.D. Salinger books? This would be meaningful and personalized since your girlfriend loves Salinger's work. You could also include a special note or letter inside one of the books expressing your love and appreciation for her. Additionally, you could plan a weekend escape to a place connected with Salinger, such as New York City, where she can visit places that inspired the author.
Or you can get her a star map with the date of your anniversary.
