Basic business directory searchable by keyword or alphabet.
Official GT&T Yellow Pages telephone directory of businesses in Guyana. Displayed as an interactive replica of the paper version, but the search tool doesn't work (couldn't find a simple request of 'hotels' nor an actual company I could see listed on a page). You need to scroll through the pages in full screen mode - not really very user friendly.
Official GT&T White Pages telephone directory of people and businesses in Guyana. Simple to use and provides addresses as well.
