Question

How does Voyager index ISBNs? Are there separate indexes for ISBN-10 and ISBN-13?

Answer

Voyager offers multiple indexes for both ISBN-10 and ISBN-13, which index one or both numbers. See descriptions below, and the Voyager System Administration guide for more information on Voyager indexes.
