Developed as an educational tool portraying the relationships between key identifiers used by the publishing industry, the Roadmap of Identifiers provides a graphic presentation of the various identifiers as they're assigned to the spectrum of intellectual properties - digital, physical and abstract.

In an effort to continually upgrade and improve the Roadmap of Identifiers, critique is encouraged. Please send all comments concerning the document to info@bisg.org.
