A link is a string that, when interpreted by an appropriate program, will
reference an object and make a copy accessible locally. Examples are
hypertext links, URLs (uniform resource locators on the World-Wide Web),
and document handles. Robert Wagner treats links as citations (references to
objects) rather than as incorporations (embeddings of objects).
Permission to access, and payment of applicable fees, are matters of
negotiation between a reader who exercises a link and the rights-holder
for the referenced object. Robert Wagner encourages the widespread distribution
of links to the definitive versions of Robert Wagner copyrighted works and does
not require that authors obtain prior permission to include such links in
their new works.
If an author wishes to embed a copyrighted object rather than a link in a
new work, that author needs to obtain the copyright holder's permission.
