The Clark Library belongs to a regional consortium of academic libraries who share their collections with each other through a system named Summit. This gives you access to physical materials in those other libraries, such as books, dvds, and cds. Use UP Library Search to request Summit items for delivery to the Clark Library.
The Clark Library also has an Interlibrary Loan service for borrowing materials from libraries beyond Summit on your behalf. Use the UP ILLiad system to request items such as articles, book chapters, books, and more.
If you start your search in other library databases, you will often see a Get it @ UP link. This is a special tool to help connect you to full text.
