I love bookish gadgets, I must say that my collection of bookmarks is growing proportionally to my TBR pile. Well, almost ;-) Bookends make also great decoration of a bookshelf, especially when they correspond to the book on the shelves, I've found several that I would really love to have.
Bookends for favorite titles
Bookends for the fantasy titles
Bookends for the sci-fi titles
Bookends for romance titles
Bookends for crime titles
