La Library of Congress a introduit la notion de liens permanents dans son Opac: lire ici (LCCN Permalinks). Des URLs stables, donc, pour les enregistrements bibliographiques de son catalogue. En lieu et place des adresses basées sur des ID de session...

Intéressant aussi: LCCN Permalink provides a qualified URL syntax to support direct persistent links to MARCXML, MODS, or Dublin Core-formatted bibliographic records. The qualifier must be added to the end of the LCCN Permalink URL. For example.

LCSH Browser, développé par l'université de Braunschweig (Allemagne):

"This database contains about 5.2 million Library of Congress Subject Headings, set up for browsing by the authority headings themselves but also by phrases and even words contained in the headings. The large majority of the records are for personal names and name/title combinations. This is in a very early stage! Little time and no funding was available for it, so please don't expect perfection.

How can this help?
Looking for publications on French poems written by female authors, what do you enter? You can try many combinations of the words French, France, poems, poetry, women, female etc. But there is one term that was established by the Library of Congress to denote the subject in a consistent way, and that term is
French poetry -- Women authors -- History and Criticism
This term is called a Library of Congress Subject Heading - LCSH.
In Library catalogs thoughout the English speaking world, chances are good that you can find the most relevant stuff if only you know this key to success. The world's biggest library catalog, OCLC's Worldcat, also makes these terms available for searching. But now, "Google Books" has started to index these magic keys as well! The only problem now is to know the one and only appropriate term as assigned by the Library of Congress. In other words, where can you browse in the list of LC approved terms to find the one to use? This database serves just that purpose. At present, though, it doesn't represent the entire content of the five Big Red Books, and the data are from 2006..."
