[InetBib] CERL and ECPA publish report that explains persistent identifier schemes

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
