Reddit reviews Exhibition Design

Another conservator piping in: you might also want to consider if you need anything special in terms of health and safety for display cases where you might put radioactive geological samples (you may or may not do that but 'earth sciences' always makes me think 'ooh, Geiger counter time!').

I'm not American so I can't recommend any training or workshops but there are a good deal of decent books out there to explore:

• Exhibition Design: An Introduction (2nd Edition) by Philip Hughes
  
  
• Creating Exhibitions: Collaboration in the Planning, Development, and Design of Innovative Experiences by Polly McKenna-Cress and Janet Kamien
  
  
• Exhibition Design by David Dernie
  
  
• Museum Exhibition Planning and Design by Elizabeth Bogle
  
  
• Basics Interior Design 02: Exhibition Design by Pam Locker
  
  
• Affordable Exhibition Design by Francesc Zamora
  
  They aren't cheap but you might be able to find some through libraries in your area depending on where you live.
  
  Congratulations, this is an amazing opportunity! Good luck and have fun. :D
