ProQuest affiliate Bowker will now include the ISO-certified International Standard Name Identifier (ISNI) in its ONIX 2.1 data feeds to retailers such as Barnes & Noble, as well as the major search engines, ensuring that authors are accurately identified in search and discovery. ISNIs are unique 16-digit codes applied to public identities. This single identifier is leveraged across many applications, syncing alternate or disparate spellings of the same name, and eliminating confusion when names are the same or alike. ONIX 2.1 is used by the book trade to automate the exchange of massive amounts of metadata about books in any format. With more than 2.3 million authors now using ISNIs, their inclusion in ONIX will significantly boost the system’s precision.
