The web version of SciFinder is available for academic use to current students, postdoctoral fellows, faculty, visiting scholars, and staff at Stanford. One-time registration is required to create a personal login ID. SciFinder is not available to walk-in visitors. Please see CAS Legal for their policies on privacy and use of CAS information.

Please note: If you are on campus, please use the direct URL for SciFinder.  If you have had trouble with your SciFinder session being lost, it appears to be due to load-balancing settings on the EZProxy server.  We are seeing if/what can be done to eliminate this problem.  In the meantime, if you are on-campus please use the direct URL for SciFinder.
