I found this word in the Ellen Lupton article labeled “Why Collaborate?” 

“I have been a museum curator for nearly fifteen years, so I am familiar with both the pleasures and pains of collaborating. “ 

When I first came across this word I found myself stumped I had not heard this word before, even trying to use context clues I could not figure out the meaning, I decided to take to the internet to expand my vocabulary and now seeing what the word means. the sentence now makes a lot more sense now fully understanding the context. showing that Ellen Lupton is experienced with collaborating for the reason of her employment of being a curator.
