The purpose of this template is to provide a single location for the base url that links to the nps.gov website. In the event that the base url is changed at nps.gov, a single change here corrects thousands of broken links.

This template uses {{NRHP url/core}}. When it becomes necessary to change the base url, that change is made at {{NRHP url/core}}.

Usage

edit

This template takes three parameters:

|id= – (required) the 'file name' without the .pdf extension
|title= – (optional) the title of the linked document
|photos= – (optional) when linking to a file in the Photos folder, setting |photos=y will modify the url path

Parameter names are not required. When not used, the positional order is:

{{NHLS url|identifier|title|photos}}

When |title= is empty or omitted, the template produces a url suitable for use in Citation Style 1 and Citation Style 2 templates.

{{cite web |title=United States Naval Academy |url={{NHLS url|id=66000386}} |publisher=[[National Park Service]] |access-date=2016-03-03}}
"United States Naval Academy". National Park Service. Retrieved 2016-03-03.

With a title, the template produces a properly marked up external wikilink:

{{NHLS url|id=66000386|title=United States Naval Academy}}
[https://npgallery.nps.gov/NRHP/GetAsset/NHLS/66000386_text United States Naval Academy]
United States Naval Academy

To link to the associated photos:

{{NHLS url|id=66000386|title=United States Naval Academy|photos=y}}
[https://npgallery.nps.gov/NRHP/GetAsset/NHLS/66000386_photos United States Naval Academy]
United States Naval Academy

To create a plain url link to the associated photos:

{{NHLS url|id=66000386|photos=y}}
https://npgallery.nps.gov/NRHP/GetAsset/NHLS/66000386_photos
https://npgallery.nps.gov/NRHP/GetAsset/NHLS/66000386_photos
