Hi, Are your books using the same calendar system? If they are, then you can probably use entity types to organise the data on your timeline by book. If you add an Entity Type called "Book" and then add Entities of this type for each of your books, and assign them to the corresponding events, then you can divide the events by book type by clicking the "Group By" icon (three horizontal bars) and choosing to group by Book. If you do this, you can also filter by each book, and then this will only display events from the one book. You can read about adding Entity types here: https://www.aeontimeline.com/support/timeline-settings/, adding Entities and grouping by entity here: https://www.aeontimeline.com/support/manage-entities/ and here: https://www.aeontimeline.com/support/getting-started/ and you can read about filters here: https://www.aeontimeline.com/support/filtering/ Doing this gives you a way to organise your events on the timeline so it is easy to see which events belong to which book. If your books have different calendar systems, then there is no way to combine the two onto one timeline at the moment. Jess
What I've done before when using one timeline for a cozy mystery series is to add all the events as usual but have one arc for each book. That way you can see everything in the global arc and each book appears in their own arc. Events can belong to multiple arcs, so I also have arcs for the mystery elements and so on.
