Libraries organize non-fiction books in category with sub-categories, using a hierarchical system, that makes it possible to find books on a specific subject.

Is there some lookup service, for example web page or database, that can provide category with sub-categories based on a books ISBN number?

  • ISBN lookup, e.g. isbnsearch.org/isbn/055380457X, only provides title, author and publication information, but there is no characterization of the contents, thus no information about how the book could be organized in a library. Mar 26 at 16:17

The Google Books API offers a category-field.

Example: https://www.googleapis.com/books/v1/volumes?q=isbn:055380457X (Business & Economics being the category).

Another example would be WorldCat. Just type in the ISBN in the search for books, and you will find categories or topics associated with that book. (They also have a machine-readable API, but you will need to register, as far as I know.)

But note that normally every library uses its own curated hierarchy of tags.
