Usage notes | An LCCN has three parts, as shown at http://lccn.loc.gov/#n9 (both left and right columns): Year: 2 digits if assigned in the years 1898-2000; 4 digits if assigned in the year 2001 or after Serial: 1 to 6 digits; best practice is now to always type this number with 6 digits, padding the number with zeroes on the front if needed. For records in Library of Congress Authorities (Q13219454), including titles of famous works, and names of people, use LCAuth identifier (Property:P244). Alphabetic prefix: A possible prefix of 1 to 3 lower-case letters. (Bibliographic records after 2000 never have a prefix, but pre-2001 bibliographic records often do, and other kinds of LCCNs always do. Bibliographic records do not have prefixes n, nb, nr, ns, sh, sj, sn: use Property:P244 for those.) On Wikidata, an optional space or hyphen may appear before the year. An optional hyphen may appear before the serial number; if the serial number is typed as less than 6 digits, the hyphen is required. The preferred and best formatting now is to remove all hyphens and spaces and insure that the serial is always 6 digits, as shown in the right column of http://lccn.loc.gov/#n9. | ||||||||||||

Name and constraint problems
[edit]The names recently given to P244 ("LCNAF identifier") and P1144 ("LoC editions" or "LCCN editions") appear to be Wikidata user inventions.
- The Library of Congress considers these identifiers to be part of the same numbering system, but with subordinate schemes. See, for example, the Library of Congress page "Structure of the LC Control Number", and the older "Library of Congress Control Number (LCCN)-- Restructuring to Accommodate Century Change", and the new catalog search http://catalog2.loc.gov/vwebv/searchAdvanced
- "LCCN editions" and "LoC editions" appear to be some transliteration from French, not English; these phrases exist nowhere on Earth except on Wikidata in the last month. This is obvious from a Google search. (To be fair, I think that the LCCN bibliographic record does usually refer to a specific edition of a book or other publication.)
- The phrase "LCNAF identifier" exists nowhere on Earth except on Wikidata in the last month. This is obvious from a Google search.
At http://www.loc.gov/marc/ there are 5 types of records: Bibliographic, Authority, Holdings, Classification, and Community. According to the Year section in "Structure of the LC Control Number", LCCN is used for all 5 of them. P244 appears to be an attempt to link to Authority records (which usually have "n" as a prefix); P1144 appears to be an attempt to link to the Bibliographic records. Therefore:
- I'm changing the wording of Library of Congress authority ID (P244) and Library of Congress Control Number (LCCN) (bibliographic) (P1144) to reflect this.
- Should the domain/scope and restraint on Library of Congress Control Number (LCCN) (bibliographic) (P1144) be more like work (Q386724) or at least literature (Q8242) rather than book (Q571)? The bibliographic records are not just for books: they include magazines, music (audio recordings), etc. For example:
- Like a Virgin (Q250406) => 95783002 (12" 33 1/3 RPM music album: Sire 9 25157-1, EAN 7599251571)
- The format constraint (|n|nb|nr|no|ns|sh|sj|sn)(|\b|-|/)(|16|17|18|19|20)\d\d(|\b|-|/)\d{6} appears to be designed only for authority records (Library of Congress authority ID (P244)) not for bibliographic records (Library of Congress Control Number (LCCN) (bibliographic) (P1144)). Bibliographic Record Prefixes in "Structure of the LC Control Number" shows a large number of alphabetic prefix options. It appears that n/nb/nr/ns/sh/sj/sn are prefixes that shouldn't appear in Library of Congress Control Number (LCCN) (bibliographic) (P1144). (To make it more confusing, apparently the prefix "no" was used for bibliographic records from 1930 to 1940, then used for authority records recently.) Is there any reason not to change the regex? Unless someone objects soon, I'll probably change the regex. --Closeapple (talk) 01:05, 22 February 2014 (UTC)
- On the previous subject: I've now updated the format constraint so it matches bibliographic LCCNs, not name authority LCCNs. The regex I created allows the number to be typed as "old format" (x 12-3456) or "new format" (x12003456). If we want to make sure duplicates are noticed, we probably want to make the constraint even stricter, to allow only the new format. --Closeapple (talk) 05:44, 22 February 2014 (UTC)
- Hi Closeapple, thanks for taking care of this difficult task, but with "LCOC" and "bibliographic" you have introduced new terms. 1) Imho "LoC" is more common. 2) We have to distinct between authority records (for works) and "regular" library records for single editions, see Wikidata:Books task force. (The terms are not of French origin. They have been chosen by the book task force based on the Functional Requirements for Bibliographic Records (FRBR) model.) Of cause these "editions" incl. all kind of media collected by the Library of Congress. Please keep in mind, if you change the labels for the LoC properties you have to change the other library properties as well. --Kolja21 (talk) 06:32, 22 February 2014 (UTC)
Bad results? Where should the "formatter URL" point to?
[edit]I've found that with newspapers, many LCCN numbers seem to come up with meaningless results, when I click on the Wikidata entry. For instance, Q55668547. Many of these LCCN numbers come from the U.S. Library of Congress "Chronicling America" web site. Any ideas what's going on? -Pete F (talk) 18:27, 3 September 2018 (UTC)
- @Peteforsyth: The
lccn.loc.gov
"LCCN" service is a strange service. It accepts LCCNs for the main and Handbook of Latin American Studies (Q27333698) OPACs acting as a sort of redirector service but it also accepts authority LCCNs creating brief pages as landing spots for such. Despite LoC hosting Chronicling America (Q5114080), not all LCCNs from that project are available in their main OPAC and thus they were previously not available via this this property. Since the formatter URL (P1630) was updated fromlccn.loc.gov
towww.loc.gov/item
this is no longer an issue (although it potentially brings up other issues like Handbook of Latin American Studies (Q27333698) LCCNs such as bi2021000008 ). —Uzume (talk) 04:38, 13 May 2024 (UTC)- I would also raise the issue that the
lccn.loc.gov
andwww.loc.gov/item
resolvers are not equivalent. The former resolves the LLCN 2002252287 for the periodical al-Ustādh, the latter does not. OpenArabicPE (talk) 15:18, 29 August 2024 (UTC) - Also note that both resolvers list a LCCN permalink, which is always
https://lccn.loc.gov/{lccn}
, despite the latter not actually resolving the LCCN provided by the original poster! OpenArabicPE (talk) 15:25, 29 August 2024 (UTC)
- I would also raise the issue that the
LoC and LCNAF
[edit]Dear сolleagues, now Library of Congress Control Number (LCCN) (bibliographic) (P1144) and Library of Congress authority ID (P244) is different source and data base (for example Sel'skiy Vestnik (Q4414024), LoC including very important information: "Has supplement" and "Supplement to"). Maybe remove the conflicts-with constraint conflicts-with constraint (Q21502838)? Too many exception to constraint exception to constraint (P2303). Library of Congress Control Number (LCCN) (bibliographic) (P1144) and Library of Congress authority ID (P244) do not contain links to each other, which is very inconvenient. — Niklitov (talk) 17:16, 24 November 2018 (UTC)
