The bookshelf is for refighting normal mobs without the need to go to their spawn area. For bosses, you just talk them where they're standing in the area. You cannot fight against bosses with the bookshelf, the game won't let you. Also, you cannot recruit monsters from the bookshelf I think. If you just want their loss scenes you can just trigger them by checking their profile in their encyclopedia, no need to purposely lose against them.

Just so you know, you only get money, XP and Job XP. No drops at all. The only reason you would use it is for raising friendship, stealing their items or for getting all their attacks in their encyclopedia. Also, sometimes you just won't get only the monster you chose. For example, if you select the Imp sometimes you get an Alraune joining in too. That's a bit stupid honestly, but oh well.
