<h3>Abstract views and document downloads by country (derived from IP address of query)</h3>
 
<p><strong>Note:</strong> The country of origin is determined by looking up the source IP address in the <a href="http://www.maxmind.com/app/geoip_country">GeoLite Country</a> database provided by MaxMind LLC. Due to the ever-changing nature of the Internet, this database can never be 100% complete or accurate, so it is possible that a small number of downloads may be reported as being from the wrong country.</p>
