Web of Science is the world's largest, high-quality interdisciplinary database back to 1965. All subject areas are covered, but the sciences are covered very well. WoS is easy to use, but it has many advanced features that make it an excellent tool for advanced researchers. See the Web of Science page for searching instructions.
