	<h1>Citation Finder</h1>
	<p>
		This tool uses regular expressions to search text for neutral citations, other citations, statutes, and regulations. It produces a list of each below. A summary section provides various other bits and bobs including links to search for all of the cases, a summary of which courts are most cited, and a list of all citations in alphabetical order.
	</p>
	<p>
		This tool does not collect any data. The inputted text is not sent to any external server or stored on this website itself. All processing is done within your web browser.
	</p>
	<p>
		See also <a href="citation-linker.html">Citation Linker</a>, to add a link to CanLII to neutral citations found in an inputted text.
