How to Format a Box Set or Anthology

Bundling several books into a box set, or gathering many stories into an anthology, is one of the best moves in indie publishing. It gives readers value, refreshes a backlist, and creates a new product from work you already own. But combining multiple books into one file introduces formatting challenges that a single book never has.

Here's how to keep a box set or anthology clean and navigable.

What You're Actually Building

A box set (sometimes called an omnibus) is several complete books combined into one file. An anthology is a collection of shorter works, often by different authors, gathered together. In both cases you're taking multiple distinct works and presenting them as one coherent book, which means one file, one cover, and one consistent design.

Why They're Fiddly

The difficulty isn't any single book, it's the seams between them. A box set has to combine several manuscripts without their styling clashing, guide the reader between books, and offer a table of contents that spans everything. Do it carelessly and you get mismatched fonts, broken navigation, and a contents page that only covers the first book.

Structure the Collection Clearly

Treat each included book or story as a major part of the larger whole. The reader should always know which book they're in. A typical structure looks like this:

• Front matter for the collection: a title page, copyright, and often a short introduction.
• Each book or story as its own part, ideally opening with its own part or title divider.
• The chapters of each book within that part.
• A single, combined table of contents that lets readers jump to any book and any chapter.

Keep the Formatting Consistent

The whole set should feel like one book, which means one design applied across every included work: the same chapter opening style, the same typography, the same scene breaks and ornaments. If the individual books were formatted separately over the years, unifying that styling is usually the biggest job.

Navigation Is Everything

In an ebook especially, a box set lives or dies on navigation. The reader needs a linked contents that reaches every book and every chapter, and the device's built-in navigation should reflect the full structure. A contents page that stops after book one is the most common box set complaint.

Print Considerations

In print, a combined edition can become thick, which affects the spine width and the gutter, so size the inside margin for the full page count. Clear part dividers between books help the reader find their place, and starting each book on a fresh page keeps the structure obvious.

Where the Right Tools Save Hours

This is exactly the kind of project where reusing work pays off. Koberger is built for authors who publish more than once: it includes series and box-set tools that combine your books into a single project, a shared section library so common pages stay consistent, and the ability to apply one design across everything. That turns the worst part of a box set, unifying many books by hand, into something manageable. Our guide to formatting a series consistently covers the same ideas for individual titles.

Bottom Line

A box set or anthology is a great product, but it's a structure problem as much as a formatting one. Present each work as a clear part, apply one consistent design across the whole thing, and above all give readers a complete linked table of contents. Get the structure right and the collection reads as one polished book rather than several stitched together.
