Digital Object Identifiers (DOIs)
DOIs are unique and permanent identifiers assigned to content at book, chapter or entry level. DOIs can be loaded into an external catalogue system to create permanent links to the corresponding item.
If following a link from your library's online catalogue to Blackwell Reference Online leads to a DOI Error page, please notify your librarian.
For further information of a general nature about the DOI System, see http://www.doi.org/.
