My Library Account Support

I’m sure that I am typing in my UDelNet ID and e-mail password correctly, but I can’t log in.

Your UDelNet ID is the part of your e-mail address that precedes the “” For example, if your e-mail address is, enter udelnetid in the “UDelNet ID” field and your e-mail password in the “password” field. When signing in to “My Library Account,” you will need to enter your UDelNet ID in lowercase.

Have you changed your UDelNet ID or password within the past 24 hours? It usually takes 24 hours for these changes to go into effect; UDelNet ID changes may take up to 48 hours to be reflected in DELCAT. (Your former UDelNet ID or password should still work if you just changed them.) For information about changing your UDelNet ID or password, click here.

Are you a member of the Osher Lifelong Learning Institute, English Language Institute, or the spouse of a University of Delaware student, faculty, or staff member? If so, you need to contact the Morris Library Circulation and Reserve Desk at (302) 831-2455 to be registered for online Library services. (University of Delaware students, faculty, and staff are automatically registered for these services.) Your UDelNet ID needs to be in your Library borrower record in order for you to use “My Library Account” or to use Interlibrary Loan.

I have a UD Public Borrower library card. How do I log in?

Public Borrowers are unable to use authenticated online services such as “My Library Account” because they are not eligible to receive the UDelNet IDs these services require. Interlibrary Loan services are only available to UD ID card holders.

I’m trying to log in using my SSN and PIN, but I’m getting nowhere.

The SSN/PIN login is no longer accepted for library applications. You need to use your UDelNet ID (UNIX username) and e-mail password.

I signed in, but it just took me back to the DELCAT Discovery screen.

Has the box where you clicked to sign in changed to say “Sign Out”? If so, you have signed in successfully. You need to click on “My Library Account” to view your account information.

I’ve tried everything that you’ve suggested and I still can’t log in. Who can I call or e-mail about this problem?

If you are having problems using “My Library Account” contact the Morris Library Circulation and Reserve Desk at (302) 831-2455 when the Library is open. For Library hours, click here.

If you are having difficulty using the Interlibrary Loan system, contact the Interlibrary Loan Office at (302) 831-2236. Office hours are 8:00 AM to 5:00 PM Monday through Friday. You can also send email to
