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.) (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)
