Science.gov now offers a free "Alert" service, created by Deep Web Technologies (DWT), that sends alerts to patron's email each week based on their area of interest in science. Science.gov, a collaboration of the U.S. Department of Energy and 11 other federal agencies, is intended to ease the process of accessing federal science information by offering the public a one stop search page that crawls government R&D results, government information resources, and databases on scientific topics. Science.gov's search capabilities are powered by Deep Web Technologies' Distributed Explorit technology.
From the Science.gov homepage individuals can set up a personalized Alerts account to allow Science.gov to do the searching for them. Users can specify the subject area as well as specific sources for Science.gov to monitor for them. Each week up to 25 relevant results from each of the databases the user selects will be delivered to the user's email account. Users can also visit their online personalized Alert Archive to view six weeks of stored alerts results and edit their Alert profiles.
