A great birthday gift for your boyfriend who loves reading could be a subscription to a book club service. This way, he can receive a brand new book of his interest every month. You could also buy him a classic book he's been wanting to read, or a latest release of his favorite author. If he likes reading in bed, you could consider getting him a comfortable reading pillow to make his time even more relaxing. Additionally, you could surprise him with an autographed copy of his favorite book, or a signed first edition of a popular book.
Or you can get him a star map with the date when he was born.
