Pika - Grouping Overview

What is a Grouped Work?

A title may be represented in many different ways; as a book, as an updated edition, as an audiobook for example, but ultimately these are all representations or manifestations of the same creation called a “work.”  A bibliographic record is meant to describe one kind of representation of that work. Pika collects all of the records describing the same work into a grouped work.

A title may be based on or derived from another work; in this case, the derivative is a unique creation that should be represented as its own work.  As an example, a movie title based on a book is a unique and separate work from the book’s work.
