Specialty aggregator

A specialty aggregator is a website that collects information from a number of sources on a particular topic or location. Like feed aggregators, specialty aggregators typically display the headline of a story, and occasionally the first few lines of the lede with a link to the rest of the story, along with the name of the website on which the story originally appeared. Unlike feed aggregators, which cover many topics, specialty aggregators are more limited in focus and typically cover just a few topics or sources.
