Head on over to Abyss and talk to Ratti to do her quest. Ratti loves to read and will ask for random books. When you bring them back to her she will give you one petpedia or healthpedia. You will need to put this on your bookshelf, as they are required to complete other quests. There is no time limit for this quest!
Once you've started Ratti's quest, she will ask you for 2 books. Bring those back to her and recieve a PetPedia or HealthPedia in return.
