If Lehigh doesn't own the material you need, you can simultaneously search several academic library catalogs in Pennsylvania through PALCI. You can then request many of the items found there directly from the owning libraries.
To login to the PALCI system, simply click here and then enter your Lehigh user name and password.
Please note: The PALCI system currently handles requests only for books. If you need a photocopy of an article, please request it through the ILL Document Delivery Request form.
