Feedback:

  • It was your classes that got me really interested in the digital aspect of libraries and that's what led me to this [Library of Congress] internship. I couldn't have gotten this without my Drexel education so I thank you for that!
  • "I took your IA class at Drexel last winter. I loved the class so much that I decided to change careers and go into UX! In fact, I have my first interview for a UX Researcher job coming up next week"
  • "This was a very valuable course... really made me stretch my mind. I will definitely use what I learned in the future. This may turn out to be the course I got the most out of, long term."
