A bibliographic LCCN has two core parts (year and serial), with an optional alphabetic prefix. These are structured: [prefix] + year + serial (English)
1 reference
Year number is structured within a bibliographic LCCN. 2 digits if assigned in the years 1898-2000; 4 digits if assigned in the year 2001 or after. These are the left most values if an alphabetic prefix is not present. (English)
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. (English)

A normalized LCCN is a character string eight to twelve characters in length. (American English)

(An un-normalized LCCN may have a serial number of 1-6 digits, which is left-filled with zeros when normalized.) (American English)

For records in Library of Congress Authorities (Q13219454), including titles of famous works, and names of people, use LCAuth identifier (Property:P244). These authority records are not bibliographic LCCN (English)
0 references
Alphabetic prefix: A possible prefix of 1 to 3 lower-case letters. (Pre-2001 bibliographic records may have an alphabetic prefix. Bibliographic records do not have prefixes n, nb, nr, ns, sh, sj: use Property:P244 for those.) (English)

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. (English)

Display forms of bibliographic LCCNs may contain spaces or hyphens; normalized forms omit them. The preferred formatting is the normalized form without hyphens and space. (English)

Normalized bibliographic LCCN = prefix + year + serial(6 digits) (English)
