This template is used to generate external links to catalog records at the United States Library of Congress] by Library of Congress Control Number (LCCN). See the Library of Congress LCCN FAQ for information on LCCNs and their permalinks.

Usage
The required parameter is the LCCN. If this is the only parameter specified, the article title is used as the anchor text:

To have the anchor text be something other than the article name, specify the second parameter, as well: This can be used when the Wikipedia page name is not the name of the work whose catalog record is desired. This will most often be the case where the article name includes a parenthetical disambiguation. See the examples, below.

Examples
In the article Dr. Seuss's Sleep Book:
 * Without specifying the title, causing the article name to be used:
 *  

will produce:
 * Catalog record for Dr. Seuss's Sleep Book at the United States Library of Congress

In the article Picnic at Hanging Rock (novel):
 * Specifying the title, rather than using the article name:
 *  

will produce:
 * Catalog record for Picnic at Hanging Rock at the United States Library of Congress

Note that the examples include the "*" for a bulleted list since this is most likely to be used in an "External links" section.
