Once a Sim reaches level 2 of the Vampire Lore Skill, they can purchase Vampire Tomes by using the Vampire Secrets > Purchase Vampire Tomes interaction on a computer. The Vampire based skill books (Encyclopedia Vampirica) can only be purchased at Level 2 Vampire Lore via the Vampire Secrets interaction on the computer. Sims with a higher Vampire Lore Skill will unlock special interactions, crafts, recipes and drinks. Sims can master Vampire Lore by researching “Vampire Secrets” on a computer, asking others about Vampire History, or reading unlocked Vampire Books.
