Checking Out A Book


Just your employee ID! If you've already checked something out, we'll have you on file. 

How does it work? 

Like any public or university library you're used to! Just come in for the book you need, bring your ID if you're a new patron, and we'll get you into the system and check the book out for you

How long are checkout periods? 

6 weeks, to start. 12 weeks, if you need an extension. I will make exceptions for longer projects (as long as no one else urgently needs the book). PE exam checkouts are also longer, from 3-4 months, though due to a limited supply you may be asked to share with co-workers who are also taking the exam. You must also be taking the next exam (if you are taking the exam in October, you may not check anything out until the April exam has passed) 

DVDs may be checked out for a period of 5 days.

Public rules and regulations

The public are welcome and encouraged to visit the library! They may do so by appointment with the librarian in advance. Members of the public may not check items out of the library, but they may use our materials for research (ask for scans within reason, take photographs of needed materials, take notes, etc.)
