A great feature in Therefore is the Notebook. All the texts, dialogs and achievements that we read, discover or complete while playing are automatically stored in the notebook. Therefore is a game full of narrative and because of that it is important to be able to read again any text or dialog whenever we want, so we can get properly the beautiful history that it narrates as well as the rich philosophic background that the game possesses.
Moreover, if in any moment we have aborted some dialog or skipped some pages of a text without noticing, they will be also added to the notebook and even more, they will be marked as no read so we can locate them quickly and have another chance to read them.
At last, in many occasions some texts or character's phrases contain relevant information about certain scenery objects, inventory items or other characters and when we read these texts the game automatically changes the descriptions of that interactive items accordingly with the new information adquired.
