Publishing has always relied on metadata. Title, author, ISBN, format, publication date, subject codes and pricing all play a vital role in making sure books can be distributed, listed and sold correctly.
But that information only tells part of the story.
Increasingly, discovery is driven by a much more human question: why would someone want to read this book?
Readers don’t think in metadata fields
Most readers do not search for books using publishing terminology. They search for things like “a funny book for a nine-year-old”, “something like The Thursday Murder Club”, “an easy vegetarian cookbook” or “a gripping historical novel set in France”.
These are intent-based searches. They describe mood, audience, theme, reading occasion or similarity rather than traditional bibliographic information.
For publishers, this creates an opportunity to think about metadata in a broader way. The better a title can be described in terms of how readers actually search and browse, the easier it becomes to connect the right book with the right person.
Traditional metadata is still essential
None of this means ISBNs, subject codes or standard metadata fields are becoming less important. They remain fundamental to the publishing supply chain.
The difference is that they are no longer enough on their own.
A subject code might tell us that a book is historical fiction. Richer metadata can tell us that it is a fast-paced family saga set in 1920s Paris, with strong female characters and themes of ambition, betrayal and social change.
That extra context is much closer to the way a reader thinks.
Metadata is becoming part of discovery
Good metadata now plays a role far beyond retailer feeds. It can help power onsite search, recommendations, related-title sections, collections and personalised browsing.
It can also help search engines and AI tools understand what a book is about, who it might appeal to and which other titles it relates to.
That makes metadata increasingly important at the very start of the discovery journey, not just at the point where a book is listed for sale.
Think about why the reader will care
Publishers can begin by asking simple questions about each title.
Who is this book for? What themes does it explore? What mood does it have? What other books or authors might appeal to the same reader? Is it suitable for a particular age group, interest, occasion or level of expertise?
Those answers can add valuable context around a title and make a catalogue much easier to explore.
They can also help surface older books that might otherwise remain buried in the backlist.
Better metadata makes the whole website smarter
The richer the information around a book, the more a publisher website can do with it.
Search results can become more relevant. Recommendations can become more useful. Collections can be generated around themes, audiences or interests. Readers can move naturally from one title to another instead of reaching a dead end.
In other words, better metadata does not simply improve the description of a book. It improves the entire discovery experience around it.
From identification to understanding
The ISBN will always tell us exactly which book we are talking about.
But the next stage of metadata is about helping systems understand something more valuable: why that book might be right for a particular reader.
For publishers, that means moving beyond metadata as a technical requirement and starting to see it as a discovery tool.
Because the more clearly you can describe why someone might love a book, the easier it becomes to help them find it.
