The International Standard Text Code (ISTC) was published as an international standard (ISO 21047) in February 2009 and is a numbering system supporting the unique identification of textual works. The different manifestations of a work (e.g. paperback book, filmscript, e-book) can be associated with the original textual work through the ISTC. 

The ISTC standard now has ten registration agencies spread throughout the world. For more information on the ISTC and its application, see

In association with the International ISTC Agency, EDItEUR has developed and maintains an ONIX format for ISTC registration. Details will be found here.

EDItEUR provides management administration services to the International ISTC Agency and assistance to the Board.
