Step 1: Sign-up

• Investigator – Anyone who is signing up as a single user should register as an "Investigator". You will be charged the 1-5 USERS subscription rate. You have the option of signing up other users in the future.
• Institutional Administrator – If you are signing up a group of individuals (e.g., at a company, organization, institution), please register as an "Institutional Administrator".

If you are Database Manager, Owner, or Vendor, please choose one of the following:

• I want to create / update a database profile. (This option allows you to either update your database profile(s) using the username and password provided by DGI, or you may create a new database profile. This option will not allow you to access other database profiles or use any of the site features.)
• I want to subscribe and gain access to the entire site along with its search features. (This option will allow you to access all database profiles and use any of the site features. This option will not allow you to update any database profile(s) or to create a new one.)
