The search everything tab covers the major database vendors such as EBSCO and ProQuest as well as the library catalog.
You can use PALCI to get books when you can't find what you're looking for at IUP. Use the link at the top of this page to access the PALCI search screen. It usually takes 2-3 days for books to arrive at IUP from other libraries. NOTE: You will not be able to request a book if it is available through IUP or if you have overdue fines.

You can also bring your call number to the reference desk and a librarian will be happy to help you find your book.
