quoting section

"Serial numbers are six digits long and should include leading zeros. The hyphen that is often seen separating the year and serial number is optional. More recently, the Library of Congress has instructed publishers not to include a hyphen."

We should provide a source. In some fashion we should mention this at Help:CS1 errors#bad_lccn. Use of the optional hyphen, rather than zero, as the sixth character from right, "leading" the serial number, must commonly be what the error message "Check |lccn= value" flags.

Using code that I don't know, we provide an official source at Category:CS1 errors: LCCN. Source url=http://www.loc.gov/marc/lccn-namespace.html#syntax

Hello fellow Wikipedians,

I have just modified one external link on Library of Congress Control Number. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

• Added archive https://web.archive.org/web/20080209121257/http://lccn.loc.gov/lccnperm-faq.html to http://lccn.loc.gov/lccnperm-faq.html

When you have finished reviewing my changes, you may follow the instructions on the template below to fix any issues with the URLs.

This message was posted before February 2018.

• If you have discovered URLs which were erroneously considered dead by the bot, you can report them with this tool.
• If you found an error with any archives or the URLs themselves, you can fix them with this tool.

Cheers.—InternetArchiveBot (Report bug) 09:13, 15 May 2017 (UTC)[reply]
