Template:Dictionary of National Biography/doc

Quick explanation (aide-mémoire)
The template can be placed in different locations and depending on the what it is required the parameters can be mixed and matched:

Deprecated historical template usage
The DNB template predates the availability of the DNB articles at Wikisource and has evolved over time. In the past, editors used the "title=" and "url=" parameters to point to articles in non-Wikisource copies of the DNB, often scans of marginal quality. As of 2013, all DNB articles are available at Wikisource, so pointing non-Wikisource articles is deprecated: use wstitle instead to point to the Wikisource DNB article. If you encounter one of these older template instances, please convert it. If you feel that the pointer to a non-wikisource instance is better for some reason, please put a wiki comment next to the template to explain why and comment on the talk page at Wikipedia talk:WikiProject Dictionary of National Biography. Except for a very few anonymous articles, each article has an attributed author. Please use the information at Wikisource to fill in the "last=", "first=", and (when it exists) "authorlink=" parameters. The "volume=" and "page=" parameters are also easy to fill in, but are less critical.
