Being able to learn out the library functions and the many roles that people have there. I also greatly enjoyed seeing and discovering the rich history of my city. Being able to get my hands on archive material was absolutely amazing. The staff I worked with were amazing and answered all my questions and offered some great advice for the future.
What I wish was different
That I was still there.
Ask questions. Don't ever be afraid to ask. Your mentors are more then willing to go out of their way to help you.
