How often will Science.gov be updated?
Science.gov will be kept current, with each component having a regular schedule for update. The listing of sites included in the browsetree will be updated every 6 weeks through submissions from the agencies. The number of sites added each 6 weeks will vary. Databases will be added throughout the year on a periodic basis. The deep Web database search updates immediately so that each search is current, and the Science.gov websites are reindexed weekly.
