The most important change is certainly the addition of Code 09 to the ONIX 3.0-only code list, List 154: Content Audience.
This code is used to indicate any text material not intended for direct presentation to the customer, but instead designed specifically for search engine indexing.
As such it’s intriguing. The optimization of search engine-based book discovery (SEO) is of ever-increasing importance. Search engines like Google, Yahoo and Bing between them are the source of over half of inquiries for a specific book or a range of books on a topic. Will Code 09 prove valuable to publishers as they continue to try to maximize the value of search engines? Time will tell.
BookNet’s Tom Richardson provides his own overview of the changes in Codelists 32.
Issue 33 of the codelists is planned for publication in late April of 2016
