Apologies for cross posting.
The Library of Congress is pleased to announce an expansion of its LCCN
Permalink Service for the Library's name and subject authority records.
These persistent URLs are based on the Library of Congress Control
Number (LCCN). As with bibliographic records, LCCN Permalinks are
displayed on authority record entries in _LC Authorities_
<http://authorities.loc.gov>.
*Create an LCCN Permalink*
Simply begin your URL with the LCCN Permalink domain name --
_http://lccn.loc.gov/_ -- then add an LCCN.
/Examples/: _http://lccn.loc.gov/n79018774_ or
_http://lccn.loc.gov/sh85026371_
LCCNs should be formatted according to the _info:lccn_
<http://info-uri.info/registry/OAIHandler?verb=GetRecord&metadataPrefix=reg&identifier=info:lccn/>
URI specification. Instructions are also available in the _LCCN
Permalink FAQ_ <http://lccn.loc.gov/lccnperm-faq.html>.
*How LCCN Permalink Works*
An LCCN Permalink retrieves a MARCXML-formatted record using the
Z39.50/SRU protocol. Both valid and cancelled LCCNs (MARC 21 fields 010a
and 010z) are searched. Authority record displays for LCCN Permalink
follow the labeled display found in LC Authorities. MARCXML and MADS
versions of the records are also available. Displays link to entries in
_LC Authorities_ <http://authorities.loc.gov> and the _LC Online
Catalog_ <http://catalog.loc.gov> -- and, where appropriate, to entries
in the _Virtual International Authority File_ <http://viaf.org> and _LC
Authorities and Vocabularies_ <http://id.loc.gov/>.
*More Information*
Additional information on this service is available on the _LCCN
Permalink FAQ_ <http://lccn.loc.gov/lccnperm-faq.html>. Specific
questions can also be sent to the Library of Congress through
_Ask-A-Librarian_ <http://www.loc.gov/rr/askalib/ask-digital.html>.
