Check out Jessamym West’s brilliant post:
How Not To Write About Libraries
1. Your library joke is tired, even if it’s new to you
2. Quit it with the wardrobe policing
3. We’re not all women, not even close
4. Many different people work in a library building
5. There are some amazing things hidden in special collections
6. No one with any credibility thinks “It’s all on the internet” and there are reasons why it isn’t
7. The money thing is complicated, take some time to understand it
8. Not all libraries are public libraries
9. The entire public is welcome in the public library
10. Libraries are full of joyful noise

Thank you, I was pleased with how it came out and I got lots of good input when I was writing it.
