Iowa condo association secretary needs help understanding condo law

I live in Iowa but am unaware of some of the HOA laws that apply for our 76 unit Condo Association. Much correspondence between the Directors and Residents is done through a director's site which was set up when ownership was transferred. Being the Secretary 2+ years, is it my understanding that any and all of the information sent/received by all Residents the property of the Association? And is it required by Iowa law to have copies of all said correspondence need to be contained within the Legal Binder of the Association?
