Template:Library resources by/doc

The Library resources by template provides text containing external links to resources in the user's preferred library (and possibly also in free online book collections) by the topic of an article. More details can be found in the documentation for the related Library resources box template.

Parameters

 * If this, or the  parameter, is set to , links are shown for free online books (as listed on the Online Books Page).  It is best to check to see if any such books are listed there.  (If not, eligible books may be suggested.)
 * If set to, links are not shown to select other libraries.
 * If set, the value is used in place of the article title in the supplied text.
 * The remaining parameters can be used to specify more precisely the topic to query in the destination library. By default, the FTL service will attempt to find a suitable library author heading based on the title of the Wikipedia article, or use the article's title in a keyword query, but you can use one of the following parameters to more precisely direct the library query.  No more than one of the following parameters should be used:
 * The author is identified by the supplied Virtual International Authority File identifier, if known.
 * The author is identified by the supplied Library of Congress Control Number, if known. Currently only LCCNs for names are supported.
 * The author is identified by the supplied authorized name or subject heading from the Library of Congress Authorities.
 * The author should be based on the supplied Wikipedia page title, instead of the current Wikipedia page's title.

Examples
The simplest template call generates text with links to resources by the current article's topic at the user's preferred library, and at other libraries, based on the title of the article. Links to online books are not shown.

This generates text with links to online books, resources at the user's preferred library, and resources at other libraries, by the whatever is identified by VIAF ID "31432428" (in this case, George Washington). Using the VIAF ID makes this link less vulnerable to possible future changes in the Wikipedia article title (or in the Library of Congress authorized heading) for George Washington.

This generates text with links to online books, resources at the user's preferred library, and resources at other libraries, by the Catholic Church (if it is placed on a page titled "Catholic Church", or the additional parameter  is set to  ). The label parameter in this case makes the text read more grammatically (as it will say "by the Catholic Church" instead of "by Catholic Church").

This generates text with links to online books, resources at the user's preferred library, and resources at other libraries, that are by the US National Park Service. The lcheading parameter is used to explicitly specify a Library of Congress subject heading to use for the library links. (A VIAF or LCCN identifier is usually preferable, but not always supported.) We also include a label parameter to label the concept in more everyday language.
