Prince William (VA) Public Library System
Welcome to Interlibrary Loan!

What is ILLiad?

Back to top

ILLiad is the electronic system you use to request an item through Interlibrary Loan. ILLiad is an acronym for InterLibrary Loan internet accessible database.

Why do I need a username and password to use ILLiad?

Back to top

Your username and password allows secure access to information about your interlibrary loan requests. We can also enable you to edit your personal information such as your address or phone number.

Your username can be anything you like, such as your name, abbreviations, or an alphanumeric code. Your password also can be anything you like. We recommend that you follow good security practices and choose a password that is different from those you use to access other systems. However, no one but you will know your password, not even the library staff. The password you set is stored in an encrypted file.

What if I forget my password?

In the event that you forget your password, please contact the Interlibrary Loan Office at
(703) 792-4894. We can then reset your password allowing you access to ILLiad. Please change your password once you login to ILLiad.

What Web browser should I use?

Back to top

We recommend the current versions of either Microsoft Internet Explorer or Mozilla Firefox.

Is security a problem if I use a public workstation?

Back to top

Web browsers cache information and create a history file on the local workstation. This allows a subsequent user of the workstation to access the system under your name using the browser's Back button to recall a page from the cache, or by finding a page with your personal information in the browser's history file.

However, if you are accessing Illiad from a Prince William Public Library System "Public Access Computer", cached information is removed when you log off.

Why does my browser say that you're sending a cookie? What's in it?

Back to top

The technology that we use sends a Session ID to be stored on your machine. You can refuse this cookie and still be able to use ILLiad without any problems.
