Technically, there's 2 :-)
- Library of Congress authority ID (P244)
<https://www.wikidata.org/wiki/Property:P244>: Library of Congress ID for
authority control for persons, works, organizations and subject headings
(for book editions use P1144). Format: 1-2 specific letters followed by
8-10 digits (see regex).
- LCOC LCCN (bibliographic) (P1144)
<https://www.wikidata.org/wiki/Property:P1144>: Library of Congress ID for
bibliographic records (for books, serials, maps, music, video, etc only;
for names use P244)

If you have an external identifier you often can find
the record you want
Worldcat can use the lccn property
See
http://worldcat.org/identities/lccn-n79005597/
That is Wikidata Q7724 <https://www.wikidata.org/wiki/Q7724> that has
property
P244 lcauth
https://m.wikidata.org/wiki/Property:P244
If you check VIAF you see The Wikidata record
https://viaf.org/viaf/54154627/ and also Lccn 79005597
https://viaf.org/processed/LC%7Cn%20%2079005597
You can also use the Lccn number and find the Wikidata record
https://tools.wmflabs.org/sqid/#/view?find=P244:n79005597
Hope it make sense.... its loosely coupled system and then it maybe is not
the best structure.....

Dear all,
I asked myself a series of questions about the links between Wikidata and
other knowledge/data bases, namely those of OCLC and DBpedia. For example:
- Why Wikidata has no property "Worldcat Identities
<https://nam03.safelinks.protection.outlook.com/?url=http%3A%2F%2Fworldcat.org%2Fidentities%2F&data=02%7C01%7C%7C24ed3d8b41df4df00fc008d58385ecec%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636559533579975247&sdata=DhHWzrQOoGjvmELLEAEXk49jehINSaIzcaSI2%2F9yWeg%3D&reserved=0>"
while the English edition of Wikipedia systematically mentions this
identity (when it exists) in its section "Autorithy control" ?
- Why do VIAF links to all editions of Wikipedia, but not (simply) to
Wikidata ?
- Why is there no link to DBpedia when the opposite is true ?
These questions may seem very different from each other, but they
ultimately concern a common subject and are all very basic. I suspect they
had to be discussed somewhere, maybe at the dawn of Wikidata. However, I
find nothing in the archives of this Newsletter, nor in the discussions on
Wikidata.
Could someone point me to some documentation on these issues ?
Cheers,
Ettore Rizza
