  • If you are still using SciFinder “classic,” I do encourage you to begin using SciFinder-n. It’s the same username and password for both systems. If you have the old URL bookmarked, it will redirect to SciFinder-n after December 31.
    • To migrate your saved searches and alerts, login to SciFinder-n, go to Saved and Alerts, then Migrate Alerts & Saved Results. There is more information about migration exceptions within the SciFinder-n help menu (link).
  • CAS has created some good training videos on SciFinder-n ( There are also some upcoming webinars, and I can offer training to classes, research groups, and individuals.
