About ISTCs

The International Standard Text Code (ISTC) is a unique identifier that links publications of the "same content" improving discoverability of your titles.

The ISTC number will improve the chance that all manifestations of the same content will be returned in a search and become available for purchase or loan.

The ISTC identifies similar text-based works appearing in conventional printed books, audio-books, static e-books or enhanced digital books.

The ISTC will make it easier for your customers to find and purchase your titles.

Contact Bowker today to get ISTCs for all your titles! For information on assigning ISTCs and pricing, please contact a Product Manager at (ISTC@bowker.com).
