Notes

  1. The Visits column (April 2009 and thereafter) shows the number of visits to the site. A visit is initiated when a website user requests a page on the HRS server for the first time. All requests from that user within a given time period are considered to be part of the same visit.

  2. The Site Accesses column (March 2009 and before) shows the number of hits on the main index page (not counting hits to any other page on the site). From February 1995 through August 2000, this number was collected by a graphic hit counter. From September 2000 through August 2002, the number was determined from the log analysis provided by the University of Michigan. From November 2002 through March 2009, the number was determined from information generated from ISR server logs using Webalizer. From April 2009 through December 2016 main index hit counts were replaced by visits as reported by Webalizer. In January 2017, site visit counts were replaced by Google Analytics session counts.

  3. The User Registrations column reflects the number of new user names submitted as part of the registration process for access to HRS data. Note: The current file download system was introduced on September 1, 2020. This required all users to register a new account, and the cumulative user registration total was reset. Registration is mandatory for all public and restricted data users.

  4. As of June 2017 the Concordance column is based on Google Analytics page views. Prior to June 2017, the column showed the total number of searches; i.e., calls to the Concordance search engine. For the period February 1, 2006 through April 30, 2009, this column showed the total number of hits for the Concordance page. For the period April 1, 2002 through January 31, 2006, this column was called Concordance Server Accesses and showed the number of unique visits to the external server on which the Concordance and Bibliography pages were hosted.

  5. As of September 2016, the Bibliography column is based on Google Analytics page views. Prior to September 2016, the column showed the total number of searches; i.e., calls to the Bibliography search engine. For the period February 1, 2006 through April 30, 2009, this column showed the total number of hits for the Bibliography page.
