Traditionally, references to web content have been made by using URL
hyperlinks. However, as links are 'broken' when content is moved to another
location, a reference system based on URLs is inherently unstable and poses
risks for continued access to web resources. To create a more reliable
system for referring to published material on the web, from the mid-1990s a
number of schemes have been developed that use name spaces to identify
resources, enabling retrieval even if the location on the web is unknown.
A recently published report explains the principle of persistent identifiers
and helps institutions decide which scheme would best fit their needs. It
discusses Handles, Digital Object Identifiers (DOIs), Archival Resource Keys
(ARKs), Persistent Uniform Resource Locators (PURLs), Uniform Resource Names
(URNs), National Bibliography Numbers (NBNs), and the Open URL, providing
examples and extensive references for each.
The report was written by the Research and Development Department of the
Goettingen State and University Library (Niedersächsische Staats- und
Universitätsbibliothek Göttingen) at the request of the Advisory Task Group
(ATG) of the Consortium of European Research Libraries. It is co-published
by CERL and ECPA.
