You may be able to visit a library near your home to get resources you need. Determine whether your public library can obtain books for you from other libraries. Many states have efficient interlibrary lending operations.
In AMBS WorldCat, you can see when libraries near you have an item. Click on the title, scroll down in the "availability" area, and enter your address or postal code in the "search location" box. The list will automatically sort so the libraries appear in order based on their distance from your location.
Libraries at public, state-sponsored universities are often required by law to offer borrowing privileges to anyone residing in the state. These libraries typically have large research collections.
