The various pre-made Sim characters in Enchanted By Nature have bits of lore or personal background that they'll share when the player selects the "Hear Tales" social interaction from the gossip category. Each time they share a new tale, a new entry unlocks in the notebook, and it seems that each of the pre-made Sims has three different tales to share.
The problem is that it appears to be impossible for the player to hear all of these tales from all of the characters on the same Sim. For example, Oberon Summerdream might share two to three of the tales he knows with Sim A, but only one with Sim B (no matter how many times the player selects the hear tales interaction), and then with the next character (Trader Joe, for example), the reverse might be true.
I can't think of a reason why this would be by design. It should be possible for the player to unlock all of the possible notebook entries on any given Sim, but that doesn't appear to be possible. I've tested this out with multiple Sims. I can't get any one Sim to unlock all of the possible notebook entries.
