Identifiers identify products so they can be ordered, tracked, and sold. BISG provides research and best practice recommendations for the use and maintenance of book industry identifiers such as ISBN, DOI, EAN, ISTC, ISNI, etc.
Many of the resources below are provided thanks to the work of BISG's Identification Committee.
This BISG Policy Statement on recommendations for identifying digital products is applicable to content intended for distribution to the general public in North America but could be applied elsewhere as well. The objective of this Policy Statement is to clarify best practices and outline responsibilities in the assignment of ISBNs to digital products in order to reduce both confusion in the market place, and the possibility of errors. This Policy Statement was initially published in December 2011. BISG always intended to revise the Statement from time to time in order to keep up with the ever evolving digital market place. To this end, a revised version was published in February 2013.
Published by the International ISBN Agency. Valid from January 2007 onward. Go to the ISBN Users' Manual.

First published in August 2005, this short PDF document defines and attempts to standardize the nomenclature surrounding product identification.
Although there are strong similarities between the identification needs of physical books and of digital book content in the supply chain, new business models and new delivery channels challenge existing practices. There is a pressing need for clarity on the use of standards for the identification and description of digital products.
