Registered user information consists of an ID, password, e-mail address, and OCLC institution symbol.

The ID and password are used to authenticate all transactions you generate against this PURL resolver's database. You must use your OCLC CONSER or BIBCO authorization (ID) and password. Once entered, a user ID and password cannot be modified. Your ID and password prevent unauthorized users from creating and modifying PURLs. You can only modify the name and e-mail address associated with an ID and password.
