1. All users must register* with CAS to establish a unique username and password. Registration must be completed with an OSU email address (ending in osu.edu, ohio-state.edu, or osumc.edu). You can only register once. If you are on campus when you register, use the on campus registration; if you are off campus when you register, use the off campus registration. (Either registration will permit future on-campus and off-campus access.)

During the registration process CAS will send you an email which is required for completion of the process. Occasionally, that email ends up in spam, so check your filtered mail if you do not receive CAS’s email. You only need to register once (if you're on campus when you register, use the on-campus registration URL; if you're off campus when you register, use the off-campus registration URL). Once you establish your username and password with the registration process, if you want to use SF on-campus, use the on-campus access URL and if you want to use SF from off campus, use the off-campus access URL.
2. After completing the registration process, users can access the web version of SciFinder with their username and password* at:
On campus access: https://scifinder.cas.org/
Off campus access: http://proxy.lib.ohio-state.edu/login?url=https://scifinder.cas.org
3. Pop-ups must be allowed from CAS (if your browser does not currently allow them, you should be prompted).
* Disclosure: CAS maintains a log of time of access and IP access address for each user. Although OSU Libraries would rarely, if ever, have any use for these logs, we do have access to them. The logs to which the OSU Libraries have access do not contain information about search parameters or downloads, however, CAS does maintain a log containing each of your search parameters and a record of which articles you chose to download. That information is held by CAS and not accessible by the OSU Libraries. A user can access his or her full search history data (including parameters and downloads) through the SciFinder interface (Saved Searches tab, History).
