Unlike most other Stanislaus State Library databases, CAS SciFinder-n requires your to create your own personal account with a username and password you choose. As long as you use the Stan State CAS SciFinder-n links (included on this guide), you should be able to register for a free account without any charge to you. Once you have registered, you can return and go straight to the CAS SciFinder-n Login link, but you will need to enter the username and password you created for your own personal CAS SciFinder-n account.
