It is not a full archive of The Gazette newspaper. You can access that by subscribing to a commercial service called Infomart. You must included your postal address for invoicing. The search is limited to stories that have been published since 1985. For research prior to 1985, please contact your local municipal library about the possibility of using their microfilm records.
University libraries are also a good source.
The engine only searches the Web site. Stories are only archived for three months. To find all of the stories that were posted on a given day, enter the date in one of the text fields above. The search engine can only find words, not phrases. It does not recognize punctuation, so if you're look for bob's llamas then search for bob llamas.
