Inner Workings of CHOAM

Hi all!

I've read the original novel, and I wondered if there were any of the later works that focused more on the inner workings of the CHOAM Corporation. The author had obviously put a siginificant amount of time and thought into the layout of the universe the novel is written in, and I was looking for more info on whether he shared a detailed account of the CHOAM background. Any assistance is helpful thanks! Great to be here.
