How do I keep character details straight across a series?

Build a series bible

A series bible is one reference document for the facts that recur from book to book. It might be a Word file or a spreadsheet, or a paper notebook. The format matters far less than having exactly one of it, kept where you will actually open it.

A spreadsheet suits the facts that change. Give each character a row and each book a column, and a cell like Book 2: left arm scarred answers the question the next draft will ask. A document suits the rest, one heading per character, with a short entry for each of these:

• Fixed traits, such as eye color, height, and accent.
• Birth year, so ages can be worked out for any book rather than remembered.
• Relationships, and when each one began or ended.
• What they know, and in which book they learned it.
• First appearance: the book and chapter, so the original wording can be checked.

The series bible template sets these out for places, objects, and the rules of the world as well.

Keeping it current

Most bibles fail the same way. They go stale: the writer fills one in before book one and stops updating it midway through book two. What helps is tying updates to a moment you already have: the end of each draft, or the day a book goes to the editor. Read the finished book once for continuity alone. Copy every new fact across, however small it seems at the time, because the scar you forgot about in book one is exactly the detail a reader of book three will remember.

When the bible and the book disagree, the published book wins, because readers have it. Change the bible. Then search the draft in progress for the character's name, and read each appearance against the entry.

Books kept in separate files make that search slower. Word and Google Docs search one document at a time, so a check across a trilogy means three searches, or a merged copy made only for checking.

In Tabularia

A series manuscript keeps every Book in one project, and that decides a lot. The project's Sheets serve all the books at once, so one person sheet covers a character from the first book to the last. Its Also known as field holds nicknames and titles, which the Sheets panel's search checks along with the name. Set the Working Scope to Entire Series and find reads all the books in one pass, stepping through each appearance in order.

Labels add a second view. Give each chapter a point-of-view label, filter the Outline to one character, and pin it as the scope; the canvas then shows only that character's chapters across every book.

What Tabularia will not do is notice a contradiction for you. Nothing compares the prose with the sheets, and a sheet does not record which book a fact belongs to unless you write that in. If each book is a separate project, the Sheets are separate too.
