I feel compelled to tell you that when it comes to finding YA e-books, you guys make it way, way harder than it needs to be. It might behoove you to hire someone who has a clue about what they're doing to get your teen fiction sections up to snuff - a librarian, perhaps. Someone who has a grasp of authority control, or even basic classification theory. Because while it may in fact be read by some teens, Anna Karenina does not qualify as teen fiction; nor, for that matter, does the Magic Tree House series. Please do something about this situation.
